Description Francesco Presel 2012-04-28 10:10:16 UTC

Application: kwin (4.8.2 (4.8.2))
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Just after logging in with KDM, while the KDE session was loading, I switched to tty1 (ctrl+alt+F1) and logged in there as well; I then turned back to tty7 (where the KDE session was loading) and found KWin had crashed

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

disable opengl shaders in "kcmshell4 kwincompositing", 3rd tab - there seems to be a bug or incompat in nvidias 64 bit drivers ...

New crash information added by DrKonqi

kwin (4.8.5 (4.8.5)) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed:

I logged in, switched to VC 1 immediately (before splash screen was gone), and did some stuff there. On my return to X a couple of minutes later, I found that the Crash Reporting Assistant was up...
