Bug 218942

Application: kwin (4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)))
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1))
Qt Version: 4.6.0
Operating System: Linux 2.6.32-020632-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
When I move over the aplication in the aplication bar in the panel, the kwin sometime crashes, also when I crash on some buttons in dolphin, don't know what can be the problem :(

The crash can be reproduced some of the times.

 -- Backtrace:
