1.2.0 crash accessing trigger prefs

[hmelman]

I was away until today, my iMac was off. I booted and QS auto-started and updated to 1.2.0

I found that my mouse trigger (hide app when moused moved to corner) didn't work. command-space worked to bring up the command window and then command-comma worked to bring up prefs. I then clicked on the Triggers button (I never remember command-singlequote) and QS crashed. This was repeatable. I could not get to the triggers prefs through any means.

Other HotKey triggers seemed to work. ⌃⌘G brought up a google search, etc. I could not mouse to the side of the screen to bring up the shelf.

I restored the QS.app from Time Machine and everything is working fine. I'm guessing the mouse triggers plugin needs to be updated. I did send in a crash report from the first crash. Let me know if there's more I can supply.

Hehe, thanks ;-)

Could you post some of the crash logs here, or if you've been uploading them to the server - let me know the name of your Mac (so I can find the crash logs relating to you)

After reading the e-mail I was (maybe) able to reproduce it.

So I re-tried the stuff I did before with QSThreadSafeMutableDictionary. It still crashed the first time I tried, but I can’t get it to crash now no matter what. My guess is that self was getting released.

[skurfer]

And for the record, I created a Mouse trigger and it worked, but a mouse trigger for Current Application ⇥ Hide didn’t, so something’s broken somewhere.

CORRECTION: The trigger was set for “Click” instead of “Mouse Entered”, so it does actually work.

I find it an incredibly useful trigger. Maybe you guys would like to try it and get used to it and have it in your configurations ;)

FYI, my mac is named Lumet.

Thanks. The crash that @hmelman had is different from what @skurfer posted:

User Comments:

Right after upgrading to 1.2.0, found a trigger that didn't work, hit, command-space then command-comma then clicked on Triggers and it crashed.

I've fixed Howard's bug in #1854. Rob's bug... I'm not sure

[pjrobertson]

...Now the other crash you had on 27th May seems to be related to your current application trigger that you mentioned (or at least, some trigger that contains a proxy)

This one I'm stumped on a bit more. Again, it's different from Rob's crash :/

User Comments:

My Safari (Toggle App) trigger didn't work, I activated QS, <E2><8C><98>' to bring up Triggers Prefs, then sorted by HotKey and scrolled briefly and QS crashed.
