Bug 376429

Application: digikam (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-62-generic i686
Distribution: Ubuntu 16.04.2 LTS

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

Selecting either "rotate left" or "rotate right" causes 4.12.0 to crash. Kubuntu 16.04.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
