-- Information about the crash:
- What I was doing when the application crashed:
Looking at a jpeg (reduced size preview), when I want to rotate it by 45º digikam crashes and terminates ("(digikam:26548): GStreamer-CRITICAL **: gstsystemclock: write control failed in wakeup_async: 9:Bad file descriptor")
I 'm running digikam 4.13.0 on openSuse LEAP 42 with the lxde desktop.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
