Bug 330611

Application: kded4 (4.10.5 "release 1")
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.24-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Log off from my account
- Unusual behavior I noticed:
After confirmed only a black screen appears with the white mouse pointer. after some time or possibly remote log in "No signal" appears on the monitor.

The crash can be reproduced every time.

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