-- 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
