Application: kded4 (4.11.60)
KDE Platform Version: 4.11.60
Qt Version: 4.8.5
Operating System: Linux 3.12.0-rc5-mic x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:

unplugging the BT dongle

I think I should add that I have bluez5 installed. KDE is a very recent 4.12 snapshot from OBS.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Dæmon (kded4), signal: Segmentation fault
