Bug 315521

Application: kded4 ($Id$)
KDE Platform Version: 4.9.5 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.7.9 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
At Kde startup, yet without being triggered by any application I get an error.
Sometimes the system freezes for a short time. Error has no observable effect on the functionality of the environment.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE démon (kdeinit4), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
