Application that crashed: kwin
Version of the application: 4.3.00 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-5.slh.1-sidux-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
same as 196350 just wanted to kill K3b which threw out the dvd in the middle of a burning session. 
Used yakuake and send it kill <pid>
