We have had the same problem. This only appeared on Ubuntu 12.04 so far.

Here it was related to having "geometry" and "size" properties in the form. To reproduce assign a simple .ui with one of these properties specified on a widget.

Workaround:
Manually delete "geometry" and "size" properties from the .ui file (open with text or xml editor)

operating_system was changed from to Ubuntu
os_version was changed from to 12.04

Same problem.

Very simple shape files and a very simple ui-file created in Qt4 Designer crashes QGIS without any warning!

No geometry, just simple text attributes with line edit forms.

(Only tested on Ubuntu 12.04 and QGIS 2.0.1)

fixed_version_id removed Future Release - High Priority

qgib · 2013-10-12T02:05:55Z

The term geometry does not refer to a QGIS geometry, but to a widget property geometry. Open your .ui file in a text editor and search for "geometry" and "size" and remove the entire xml element (@ to @) .

I experienced the same issue now on Ubuntu 13.10 64 bit with QGIS 2.2. The custom UI was working perfectly under QGIS 2.0, but since QGIS 2.2 the application crashes when I try to open the form via the identify tool. The fix proposed by Matthias Kuhn is not helping.

Hi Stefan. Can you attach the .ui file you were trying to load?

Concerning the original bug, I think closing this and reporting a bug on ubuntu will help more than keeping this issue here open.

Loads fine for me, but I'm not on Ubuntu. Would be nice if someone with Ubuntu (13.10) could verify.

One can try to file a bug in the official Ubuntu bugtracker (I guess that's https://bugs.launchpad.net) as it seems to be a problem of their qt libraries.

I can verify. I have same problem like Klas Karlsson and Stefan Sylla as above on Ubuntu 13.10 32 bit with QGIS 2.2. But on Windows 8 64 bit with QGIS 2.2 work fine that shape file and ui file which kill the QGIS on Ubuntu.

I've had the same problem.
On my small test files, removing geometry properties from the .ui file works.
I've tested Akbar's file both with and without geometry XML properties (xubuntu 13.10 upgraded from a 12.10) and it does not work.
Matthias, do you have more clues ? It seems to come from QT, within their QUiLoader ... but can't find anything related

qgib · 2014-04-12T01:29:37Z

Author Name: Matthias Kuhn (@m-kuhn)

Personally I've got no problems on my Linux systems (Fedora). I've only observed this happen on Ubuntu 12.04 and found the geometry property workaround with some debugging.

I assume it's a Qt bug. You could try to create a small sample pyqt script to load that ui file and see if it crashes as well. If yes it would be a nice attachment for a bug on the ubuntu tracker.

Following Alexandre report on the dev mailing list [subject: Users Manual Form annotations challenge], I've created a simple python script to open the form outside QGIS in Ubuntu 12.04 (to open his form https://www.dropbox.com/s/4a3mqni2becruh9/annotations_form.ui).

The script is:

import sys
from PyQt4 import QtCore, QtGui, uic
form_class = uic.loadUiType("annotations_form.ui")[0]
class MyWindowClass(QtGui.QMainWindow, form_class):
    def __init__(self, parent=None):
        QtGui.QMainWindow.__init__(self, parent)
        self.setupUi(self)
app = QtGui.QApplication(sys.argv)
myWindow = MyWindowClass(None)
myWindow.show()
app.exec_()

The form opens, but it is not enough to decide if it is a QT bug or not.

I had this issue in (QGIS 2.6) Ubuntu 12.04, Mint 13, Mint 17(=Ubuntu 14.04). All had core dump.

(I could not test it on Ubuntu 14.10 since it didn't have dependencies QGis required. Works fine on MacOSX)

So what could the problem be?

I don't know if it's a Qt bug but if it could help this is the situation on my PC.

With my form, QGIS master still crashes. Sandro, what was the form that you tried?

I really hope we can just close this with QGIS 3.0 (probably due to the update to Qt 5).

I have the same problem on Ubuntu where:

QGis 2.14 is installed through repository,
QGis 2.18 is compiled from source.

Loading UI file in QGis 2.18 or in minimal stand-alone Qt application will result to a crash (only when loading custom widgets).

Loaded modules analysis shows that the following module is used:

@/usr/lib/x86_64-linux-gnu/qt4/plugins/designer/libqgis_customwidgets.so.2.14.16@

even if I use stand-alone Qt app. The same is loaded with QGis 2.18 version.

Workaround:
I can remove crash by deleting this library. QGis 2.18 loads successfully forms. QtDesigner fails to load custom widgets but only warnings are reported.

Fix:
I can fix this issue on my machine - keeping @libqgis_customwidgets.so.2.14.16@ installed - by forcing @QUILoader@ not to use this plugin by resetting its plugins paths:

@QUiLoader loader;
+loader.clearPluginPaths();@

(This object is used 3 times in current QGis 2.18 source code)

Clément: good catch !

Do you know why 2.18 is linked to the 2.14 version of custom widgets ?

There is no linking between dynamic libraries. @QUILoader@ loads itself all plugins available in search paths. If @libqgis_customwidgets.so.2.14.16@ is deployed in standard Qt plugin path it will be loaded by @qtDesigner@ or @QUILoader@ instance for creating custom QGis widgets. There seams to be no mechanism that can check for QGis plugin version (only between Qt versions).

@libqgis_customwidgets.so.2.14.16@ is linked to @libqgis_gui.so.2.14.16@

By calling @QUILoader::pluginPaths()@ we can see that Qt stores some paths like @/usr/lib/x86_64-linux-gnu/qt4/plugins/designer@ (maybe hard-coded).

I try to manually deploy libqgis_customwidgets.so.2.18.10 to Qt standard path & it works (keeping version 2.14 in the same path).

But because custom widgets implementations are stored into QGis shared libraries (@libqgis_gui.so@ ?) & QGis doesn't need @libqgis_customwidgets.so@ I have clear all plugin paths for all @QUILoader@ to keep QGis custom widgets plugin in standard path (and allow uses of QtDesigner) & to force QGis to ignore these hard-coded paths.
