Bug 343220

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:
sometimes in the last few weeks I get crashes.
This is one backtrace from today.

Only thing what might be worth knowing is that I resumed the Laptop from Sleep-State shortly before the crash happend

The crash can be reproduced sometimes.

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