New crash information added by DrKonqi

gwenview (16.04.1) using Qt 5.6.0

I close Gwenview after play a gif and the Gwenview crash.

I crashed it two times in a row, but now I cannot make it crash again.

what I did:
- open some png
- alt+up to see folder
- open another png
- space to select next image
- until last which is an animated gif
- see first or second frame of animation
- alt-up to see folder again
- alt-up to see parent folder
- alt-f4 to exit
- crash
The last three alt-? came pretty fast in less than 3 seconds. I speculate, there is a race condition with the animation timer somewhere.
