Bug 236326

KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.2-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
Each time I log with KDE, I get a black screen after a white top left square.
This happens since I updated my KDE to 4.4.2 version.

The crash can be reproduced every time.

 -- Backtrace:
