Application: gwenview (4.14.0 pre)
KDE Platform Version: 4.14.3 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.14.14-gentoo_build20141105 x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
I cropped an image several times. The image size was initially ~1600*900 (a screenshot), the final size was going to be 1024*768. I cropped it three times, subsequently decreasing the size, finally I tried to decrease the size to 1032*768, pressed the "crop" button and got a segfault.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
