Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Nothink. I only input my login name and password or allow to retreive this information from Kwallet. I uses this widget in old plasma version and after update this bug occurs any time, when I tries login. I reinstalled system(update from OpenSUSE 11.2 to OpenSUSE 11.3 with LiveCD) and removes my settings, but the bug still exists.

Very interesting is plasma don't asks me for login into opendesktop account after login on my desktop session. It only asks for it after crashing(ex. I kill plasma and run again). This could been happened by NetworkManager.

- Custom settings of the application:
I uses Social Desktop widget.

The crash can be reproduced every time.
