New crash information added by DrKonqi

gwenview (4.14.0 pre) on KDE Platform 4.14.17 using Qt 4.8.7

- What I was doing when the application crashed:
I was entering fullscreen mode.

- Unusual behavior I noticed:
The screen became unresponsive temporarily, and it looked like it was only partially fullscreen (the image wasn't scaled to fill the screen, but the title bar and taskbar had disappeared.)

Is anyone able to reproduce this using a more recent version of Gwenview with KF5 and QT5?
