Application: gwenview (16.12.0)

Qt Version: 5.7.0
Frameworks Version: 5.29.0
Operating System: Linux 4.8.14-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Gwenview crashes on 'go to next image' when viewing a .webm or .mp4 file. It crashes irrelevant of method used to achieve 'go to next image' e.a. toolbar button clicker or mouse wheel used or keyboard shortcut used, it's irrelevant if the next item is a picture or another video file. Playing or paused status of the video being viewed also doesn't matter. I don't have any other video file types in my pictures folder to test if it crashes with other video formats as well, so I'm reporting for the two that I do have.

The crash can be reproduced every time.
