Application: kdeinit5 ()

Qt Version: 5.4.1
Operating System: Linux 3.19.0-17-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
using the plasmoid to connect to my telepathy kde messenger		
- Unusual behavior I noticed:
kdeinit is crashing always and the messenger cant connect.

The crash can be reproduced every time.

-- Backtrace:
Application: kdeinit5 (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
