Bug 285751

Application: kded4 ($Id$)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
KDE was starting.  The network manager asked for a password (which was already filled in correctly).  The network manager login window remained active during and after the crash.  This has happened the last three times I have started KDE (the crash).

- Unusual behavior I noticed:
Before this problem, network manager still asked for a password every time I tried to log into any wireless network (even though it already had one in most cases).  This is a problem by itself and may or may not be related to the crash.  Before the crash behavior began, KDE would take an excessive amount of time to load, after displaying the desktop and task bar.  This still happens.

If it makes a difference, I disabled KWallet.  This should not cause the behavior of network manager, but could be related.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
