Bug 343274

Application: kdeconnectd (0.1)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
I was just working on some C++ coding, when suddenly kdeconnect crashed.
It happens sometimes and I can't see any relation to the current work I do to kdeconnect
(e.g. no incoming call, no SMS, ...)

The crash can be reproduced sometimes.

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