DigitizingTools causes QGis 3 to crash (on Mac)

[dd-a]

Whenever I simply try to activate the plugin by checking the activation box in the plugin manager QGis (3.0.2 from Kyngchaos) crashes immediately. This affects versions 1.1 and 1.0.1 of the plugin on Mac OS Sierra (10.12.6).

[bstroebl]

Another user reported similar problems for Win10. Unfortunately I have neither Win10 nor a Mac available for testing; I had no problems on Ubuntu 16.04 (64 bit).
Could you please try to unload all other plugins to verify the problems are related to this particular one.

[dd-a]

I just did, with the same result. Is there any specific python library required by DigitizingTools that could be missing on my system ?

[bstroebl]

nope, furthermore in that case there should be an error report instead of a crash
Could you try with QGIS 3.0.3?

[dd-a]

As soon as it will be available I will and let you know.

[bstroebl]

I updated on Ubuntu this morning. But beware: I am not sure this will change anything, it is just a try

[bstroebl]

Maybe this is related?

[dd-a]

I don't know. This is exceeding my skills, but I don't have that error and the processing plugin loads correctly.

[dd-a]

Bad news : QGis 3.0.3 doesn't fix the issue.

[bstroebl]

There are issues pending for Win7 (#30) and Win 10 (#29). In Win 7 deactivating all other plugins made DigitizingTools loadable. Could you please try if this is the case for you, too?
Which localization are you using?

[dd-a]

I tried this morning and it crashed the same.

[bstroebl]

It may be possible that the Qgis2threejs plugin causes the issue. Please try if unloading Qgis2threejs solves the problem.

[dd-a]

Nope, it was not even installed.

[bstroebl]

So to sum things up: QGIS crashes when you try to load the plugin, no matter if any other plugin is loaded or not.
Please try the new version 1.1.1 of the plugin and check if it soves the issue.

[dd-a]

That's exactly what's happening and unfortunately version 1.1.1 did not solve the issue.

[bstroebl]

Thank you for trying, nevertheless. I am sorry to read 1.1.1 is not better (I fixed an issue that randomly gave me a runtime error). But I have no possibility to reproduce this problem on a Mac.

[dd-a]

I understand. Just ask, If you have another idea some day.

[bstroebl]

My idea would be to stay tuned and retry with any new major version of QGIS. Would be great to get feedback once the problem is solved. I leave this ticket open until then.

[dd-a]

Just to inform you that nothing has changed with QGis 3.2 and version 1.1.5 (and Mac OS 10.13.6). Still crashing.

@xsaiama
This has already been reported and (partly) solved. This thread is on MAC, if you have new information on Win7 please report it in the other thread.

[xsaiama]

Sorry. Can you delete my message, since it is not useful in this thread? I can not wait to use the essential DigitizingTools in Qgis 3.XX. In the meantime, I'm using Qgis 2.18. Regards,

Does deactivating Qgis2threejs help in your case?

[xsaiama]

I uninstalled all the plugins and then installed Digitizing Tools.
It works now. I then reinstalled the other plugins one by one except Qgis2threejs then it's still going.

Thank you.

I have just updated my machine to the Xubuntu 18.04 LTS:

$ lsb_release -a
LSB Version:

The machine is a Asus Republic of Gamers:

Upon installing Qgis it was offered the Qgis 3.2.0:

Until the upgrade I was using the last inception Qgis 2.18 in the
Qgis stable repository:

$ cat /etc/apt/sources.list.d/qgis-stable.list

http://www.qgis.org/en/site/forusers/alldownloads.html#ubuntu

deb http://qgis.org/debian bionic main

deb-src http://qgis.org/debian trusty main

nightly binaries.

deb http://qgis.org/debian-nightly xenial main

I am still finding my way on this new version.

I have installed the DigitizingTools plugin version 1.1.5 from the oficial
repository. On start os Qgis the issues the mesage:

WARNING Plugin DigitizingTools : The plugin will be disabled
because it crashed QGIS during last startup. Please report an issue and
re-enable the plugin when the problem has been solved.

If I try to activate it in the Plugin Manager I got this message at
the terminal:

QGIS died on signal 11Could not attach to process. If your uid matches
the uid of the target process, check the setting
of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user.
For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation

As for the above thread, I uninstalled the Qgis2threejs plugin and it sill crashes.

Is there any procedure I should use to help detect what the problem
is?

[bstroebl]

Hi Fernando,
sorry for the late reply, I had been on holidays.
This thread is on the plugin crashing QGIS on Mac, anyways, I never had any problems (except the Qgis2threejs thing) on Ubuntu 16.04 (Gnome). My first advice would still be to deactivate all other plugins and then restart QGIS and retry loading DigitizingTools.
Please see this QGIS webpage on creating more helpful messages (no guarantee I can make anything useful out of it).

[FernandoRoxo]

Hi Bernard,

I am afraid to be kind of hijacking the Mac thread on the subject, the point is that was the closest issue I fount to report my problem.

I have followed your suggestion and just deactivated all other plugins and, as expected, the digitizing plugin came up without crashing Qgis. Then I started to reactivate the others plugins and deactivated and reactivated the digitizing plugin. With the digitizing plugin activated, there were two plugins that I was able to activate (OSM Tools and Qgis2threejs) and after that I could deactivate the digitizing plugin but upon reactivating the Qgis crashed. With all the others I have installed no problem showed up.

I have Qgis 3.2.1-Bonn installed from the Qgis stable repositiry on [Xu|U]buntu 18.04 LTS. To be absolutely honest, it is not a new installation, I had a 16.04 LTS upgraded to 18.04 LTS, so it is possible that some remaining from the previous version can be playing in the shadows.

Please, let me know it I can provide any more info that could help in any way.

[bstroebl]

I am running Ubuntu 16.04 which has an older Qt (5.5.1) than yours. Maybe that's why loading OSM Tools and DigitizingTools in parallel is working for me.
All I can do is to advice you to not use the plugins at the same time. This is definitely annoying but the cause at least in case of QGIS2threejs is the other plugin and not DigitizingTools (see the issue I opened there).
No idea if OSM Tools is similar, though.

Hello Bernard,
I also found that go2streetview in parallel with Digitizing Tools causes the crash of QGis (3.2.0). I just made a brand new install of my system and installed the QGis extensions one by one and testing the activation of DT each time. Not only must the other one be de-activated, it must also be uninstalled and QGis restarted.

[FernandoRoxo]

I don't know the system dd-a above is using and I don't need the go2streetview plugin, but just in order to tray to gather as much information as possible, I have installed this plugin and I can confirm that in [Xu|U]buntu 18.04 and Qgis 3.2.1 if I disable the DigitizingTools and enable in sequence, the Qgis crashes.

HTH

After restarting Qgis I have uninstalled the go2streetview and after that I have reenabled the DigitizingTools, Qgis immediately crashed. Upon restart I reenabled the DigitizingTools plugin without problem.
