Bug 351384

Application: gwenview (5.0.0 pre)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

I had clicked the X in the corner of the Gwenview window to close it, then it popped up and said I had unsaved changes. I hit discard, the window went away. Then I got the crash notification.

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