Bug 315981

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I tried to add a new widget.
- Unusual behavior I noticed:
I saw a lot of characters very closed in the down left corner of the desktop.

The crash can be reproduced every time.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
