Application: kwin (4.5.00 (KDE 4.5.0))
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was testing Daisy dock for first time, and when I was switching apps, KWin crashed, altough I'm not very sure if this has anything to do with the crash, so I'm note sure if I0ll be able to reproduce it.

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