Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.38-2-helio i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was restarting knetwork exactly to get services up.

- Unusual behavior I noticed:
In general, after a restart, my KDE is coming up without kwallet services working accordingly.  So I need to restart all services dependant, including knetworkmanager.

The crash can be reproduced every time.

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