Application that crashed: plasma-desktop
Version of the application: 0.3

Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-amd64 x86_64
Distribution: Debian GNU/Linux 5.0.3 (lenny)

What I was doing when the application crashed:
KDE4 crashes after succesful login. Then I can run applications with Alt-F2. The .kde/Autostart works well launching other applications.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
