Crashes QGIS or corrupts data: Copied to github as #:13897

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

#1 Updated by Giovanni Manghi almost 13 years ago

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

#2 Updated by Giuseppe Sucameli almost 13 years ago

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.
