The KFileItem.mimetype() returns mimetype "video/mpeg" for such files.
So this could be considered a bug in the mimetype detector.
And the kio thumbnailer passes on this file to ffmpegthumbs that in turn
crashes.
STEPS TO REPRODUCE
1. Open dolphin
2. Turn on preview in the information panel
3. Hover over a .sub file
OBSERVED RESULT
Krash notification
Dolphin treats the file as playable video
EXPECTED RESULT
No KCrash notification
Dolphin shows an icon for a subtitle file.
