Application: kded4 ($Id$)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.4.6-030406-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
- What I was doing when the application crashed:
Trying to start the system, happens random each startup.

- Unusual behavior I noticed:
HDMI trouble + screen blinks every 10-20 sec at random intervals.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
