Bug 314912

Application: systemsettings (1.0)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
i selected a splash theme and pressed the test theme button. After the theme test completed the drkonqi was already up and telling me that systemsettings crashed.
- Unusual behavior I noticed:
During the test theme run i was unable to stop the test with any mouse or keyboard input (tried Escape, enter, left+right mouse click)

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
