Bug 310234

Application: systemsettings (1.0)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.6.6-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
1. Modified a global key shortcut, without "applying" the changes
2. Gone to the custom shortcuts list to delete the aforementioned entry, when a pop-up appeared "there are unsaved changes"
3. Pressed ESC a few times to get rid of the warnings and choose to delete the aforementioned custom shortcut entry --> CRASH

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
