Application: kwin (4.6.1 (4.6.1))
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: System was suspended, crashed upon re-entry fron screensaver. Error messages in backtrace spat out something about the Intel DRI stack. Possibly just an X bug? Desktop effects were enabled at the time, haven't attempted to suspend/resume without the bling.

The crash can be reproduced some of the time.

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