Bug 331037

Application: kded4 (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.11.10-7-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
When i plug the bt usb dongle, I receive an alert that KDE was crashed. Howewer when I close the alert window, I can use the bluetooth functions without problems: I have the BT symbol in the taskbar, I can open it, configure, connect and disconnect BT devices. 
If i disconnect and reconnect the dongle I don't get the crash anymore. I get it only on the first plug.

The crash can be reproduced every time.

-- Backtrace:
Application: Demone KDE (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
