Bug 370977

Application: gwenview (16.08.1)

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.7.6-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Played a video, pressed space to pause -> crash

This happens every time. When I presse ESC instead, I can get back to the browse overview without crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
