Application: gwenview (4.14.0 pre)
KDE Platform Version: 4.14.21
Qt Version: 4.8.7
Operating System: Linux 4.4.14 x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
I was rotating multiple images that had been shot with the wrong orientation. After rotating a certain number, I clicked on "save all" button, and the program crashed. This is almost sure to happen, provided a high number of rotated images get saved (> 50 )

The crash can be reproduced sometimes.

-- Backtrace:
Application: Gwenview (gwenview), signal: Aborted
