Bug 311926

Application: kded4 ($Id$)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.3
Operating System: Linux 3.6.10-2.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- Unusual behavior I noticed:
During the day or when I'm away I get a message that pops up saying the KDE Daemon crashed. Nothing happens that I'm aware of but it keeps popping up.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
