-- Information about the crash:
I was trying to copy a CD which was scratched so k3b tried again and then just froze up for like 5 minutes. After that I tried pressing close and the x buttons repeateadly since it was still frozen, that in turn crashed the Kwin, k3b was still not killed so after restarting Kwin I used alt F2 killall k3b.

 -- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
