Application: knotify4 (4.14.6)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

In my media file are pictures and video clips. When clicking the pickture, Qwenview opens the picture. When clicking -> next picture/clip Qwenview crashes. It does not happen when clicking from picture to picture, only when next is a video clip.

Regards Ulf Silzner

The crash can be reproduced every time.
