Application: kded4 ($Id$)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.1-2.fc16.i686 i686
Distribution: "Fedora release 16 (Verne)"

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

I'd just logged into KDE.  This happens every time I log in.

- Unusual behavior I noticed:

plasma-desktop has locked up, using most of one CPU and not doing anything.  The notification area, system tray and toolbars are unresponsive.

The main menu and right-clicking on the desktop works, and I can alt-tab between applications.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
