Bug 376545

Application: kded4 (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
- What I was doing when the application crashed: 1. pull the Mouse Stick from USB_Slot, because mymousepad is by Linux -start not recognized and after such action is available again. 2. push the power supply plug in the wall socket, because the Start was with the Laptop accu.

- Custom settings of the application: no application started

-- Backtrace:
Application: KDE-Dienst (kded4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
