            Bug ID: 353141
           Summary: Clicking to dismiss notifications causes crash
           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: jesuspi6127 at gmail.com

Application: kdeconnectd (0.1)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: clicking to dismiss a
notification in the widget causes the application to crash immediately.
Reloading the widget usually fixes it for a few hours but the crash eventually
reappears

The crash can be reproduced sometimes.

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