Application: kwin (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
every time i try to empty my trash can, and KDE will show me the popup to empty it or cancel then i get this crash.
Might be that it is not a real problem maybe some desktop effect that i should disable.
But it has worked correctly only now i get it every time.
Afterwards i can reenable the desktop effects without any problem.

The crash can be reproduced every time.
