#3839 closed bug (fixed)

qgis trunk crashes when saving project or clicking "OK" in the "new shape" dialog (or when using other dialogs)

Reported by: lutra Owned by: rblazek
Priority: critical: causes crash or data corruption Milestone: Version 1.7.0
Component: Build/Install Version: Trunk
Keywords: Cc: jef, alexbruy
Must Fix for Release: Yes Platform: All
Platform Version: Awaiting user input: no

Description

Confirmed under Ubuntu and Windows.

Program seg faults. The responsible seems to be part of the code of the new "customization" feature 

 QgsCustomization::preNotify (this=0x861c720, receiver=0x98c9d70, event=0x98e6420, done=0xb16d4f7f)
at /home/brushtyler/projects/sources/qgis/src/app/qgscustomization.cpp:841

More crashes for example when clicking "ok" or selecting files in various raster menu tools. 

Debug: /home/brushtyler/projects/sources/qgis/src/app/qgscustomization.cpp: 794: (customizeWidget) p = /Customization/Widgets//QFileDialog/ on = 1
Debug: /home/brushtyler/projects/sources/qgis/src/app/qgscustomization.cpp: 860: (preNotify) click
Fatal: ASSERT: "d" in file /usr/include/qt4/QtCore/qscopedpointer.h, line 112

It occurs closing non-native file dialogs (look at the difference between Save project and SaveAs project dialogs), either by pressing ok or cancel buttons.

Adding a check to exclude QFileDialog instances (as done for not QDialog instances) doesn't work as expected. In fact the problem is at line 841 trying to cast QObject to QWidget because the object was deleted yet before the preNotify was called.

I've attached a backtrace.

Confirmed under Slackware with latest self-compiled sources (c3e161a).

Seems Windows builds not affected (tested with ef981f1)
