            Bug ID: 343274
           Summary: crash while just working on something else
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: kollix at aon.at

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".
