Bug 242803

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Every time I login I see a little empty ghost window on my upper left corner, just beside the menu. if I try to close it, Plasma crashes and when auto-restores, the ghost is gone

I've upgraded my system to 4.6 and KDE did not worked until I erased my ~/.kde4 files

The crash can be reproduced every time.

-- Backtrace:
Application: Espai de treball del Plasma (plasma-desktop), signal: Segmentation fault
