Application: gwenview (16.08.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.0-59-generic x86_64
Distribution: Maui

-- Information about the crash:
- What I was doing when the application crashed: I had just cropped the image. I could see the cropped image

- Unusual behavior I noticed: I had created the image using xsane, which was still running when I first tried to crop it. I closed xsane but the exact crash repeated several times. I have not tried in a new session.

The crash can be reproduced every time.

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