Bug 289789

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
Logging in. After inserting username & password, startup "toolbar" appeared as normal but crashed with blank screen before desktop appeared.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
