When switching from desktop 1 to desktop 4 (running kuickshow in fullscreen mode and on all desktops amarok), kwin aborted with the below bt. After restarting kwin, there were only two (instead of my normal 7) desktops available, the window style was switched to keramik (normally ModernSystem). I restarted the X server (maybe kdesktop would have been enough?!) and now the selection text color was suddenly black (normally white). All very annoying, but this very report is about the kwin crash.   :-)

From gdb:
Program terminated with signal 6, Aborted.

I have one tiny local change in geometry.cpp that doesn't seem to be related. So feel free to dismiss the bug report.  :-/
