Bug 311735

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Startup is normal until the system loads KDE desktop. Plasma (I think) completely blacks out the desktop. I can still start programs by alt-f2 and I can ctrl+alt+del and logout, but the desktop stays black :-/

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".
