Application: digikam (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-34-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I pressed on the rotate image to right icon. This crashed digikam. 
This behaviour is reproducible and happens in the overview as well as in the fullscreen mode,
also left or right does not play a role.
 The error occurs on Ubuntu 16.04 on 
x86-64 platform as well as on a 
android (Raspberry pi).

The crash can be reproduced every time.
