Description Felipe Sateler 2011-10-21 23:08:58 UTC
Application: kwin (4.6.5 (4.6.5))
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

If I go to System Settings, then Desktop Effects, when enabling the desktop effects kwin crashes a few seconds after clicking apply. KDE continues to work normally, but desktop effects are not enabled.

The crash can be reproduced every time.

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

driver bug
disable blurring, down- or upgrade mesa, or force direct rendering

export KWIN_DIRECT_GL=1

depending on your GPU/driver this might fail elsewhere (esp. w/ fglrx - use the radeon driver in case and if you can)
