-- Information about the crash:
I can reproduce this crash with my currently installed netbeans 6.8. Other applications are not affected by this bug (as far as i know and as far as i tested). KWin crashes only if the Netbeans program window is maximized to fit the screen and compositing is enabled. Thanks

The crash can be reproduced everytime.

 -- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
The current source language is "auto; currently c".
