Bug 288994

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.1.0-1-686-pae i686
Distribution: Debian GNU/Linux testing (wheezy)

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

Logging in.  This crash is the first thing that happens, and I don't get any desktop.

No icons, no panels, no nothing.

Pressing ALT-F2 does get me a "run"-box though, so *some* things work apparently.

The crash can be reproduced every time.

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