-- Information about the crash:
Every time i disconnect my Dell Docking station, which is connected to two other screens, most windows that were on the other screens crash and kwin files a report.
These crash are catched by firefox, thunderbird and kwin crash handlers.

Please let me know if you want any other information, like my lspci data, or my kernel log
(i do know about unix systems, so i can switch to source version if needed, don't hestiate to ask)

The crash can be reproduced every time.

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