- 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.

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)
