-- Information about the crash:
- What I was doing when the application crashed:
Leave the computer and the monitors sleep. I don't hibernate or sleep other than the monitors. When they wake up the  desktop has changed. The wallpaper is wrong. I'm missing one of the taskbar panels on one of the monitors and the crash reporter says kwin crashed. It happens everytime the screens wake up now.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
