Bug 274548

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I'm switch off desktop effects then switch on desktop effects. Then has tried to logout

- Unusual behavior I noticed:
After effects switching on, opacity was 100%. After plasma crash and restore, opacity returns to normal state

-- Backtrace:
Application: Оболочка Plasma (plasma-desktop), signal: Segmentation fault
