Description Irwin Hutchinson 2011-09-30 14:33:54 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: Linux Mint 11 Katya

-- Information about the crash:
- What I was doing when the application crashed:
First time I was running laptop on battery and while I was away it went to sleep. On plugging in computer, the password box was only space for password.  When I typed in password, normal working seemed to resume but I got the crash notice.
Second time, screensaver was active, when I resumed, the password box was only space for password again and again everything seemed normal but I got the crash report.

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

New crash information added by DrKonqi

kwin (4.6.5 (4.6.5)) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.2

- What I was doing when the application crashed:

Testing OpenGL screensaver, seg fault happened when i shook the mouse to get out of the test. Kwin crashed. Does it consistently and is easily reporoducible. I'm on a thinkpad X1, standard config, i5-2520M with integrated Intel HD graphics.

Thanks
