Description jonathan_haas 2011-05-06 12:00:27 UTC

Application: kwin (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

at the time I was browsing the web using Firefox while developing Java applications. I didn't do something special when it crashed, perhaps moving/focusing a window or something similar.

The crash can be reproduced some of the time.

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