Bug 293433

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.3-2.fc16.i686.PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Started PC normally . Used yum to update (to kernel-PAE.i686 0:3.2.3-2.fc16 and firefox.i686 0:10.0-2.fc16). Now login to KDE causes crashdump and there is no taskbar.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
