Bug 218917

Application: kcmshell4 ()
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) "release 197"
Qt Version: 4.6.0
Operating System: Linux 2.6.31.5-0.1-default x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
As already documented by others, exiting the Global Shortcuts Editor leads to a Segfault. I'd like to just add that it happens also when launched stand-alone (i.e. not inside systemsettings). It often happens, not always though.

This time I launched it from a notification that an application (KNotes) registered new global shortcuts, giving me the option to launch kglobalaccel.

The crash can be reproduced some of the times.

 -- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
