Application: kwin (4.5.5 (KDE 4.5.5))
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.10-74.fc14.x86_64 x86_64
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
- What I was doing when the application crashed:
Using nvidia card (1:260.19.29-1.fc14.4 - Quadro NVS 285), Desktop effect activated by default, I log to my system as usual, and kwin crash. Then desktop effect has been disabled automatically.
I tried to re-activate it (several weeks ago, I had quite the same, but re-enabling effect, and all were working fine) and now, systematically, kwin crash again.

I have to check if sharpen effect is at the origin of the crash, as identified in the possible duplicate bug.

The crash can be reproduced every time.
