Operating System: Linux 2.6.32-21-generic i686

-- Information about the crash:
After typing username and password (and pressing ok) the KNotify shows a crash window and the desktop never starts (only logout option is available when pressing ctrl+alt+del)

The crash does not seem to be reproducible.
