Application: digikam (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-36-generic i686
Distribution: Ubuntu 16.04.2 LTS

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

When I opened digikam, I choosed a folder in the left panel. Then opened one folder in which were some pics with wrong rotation. So I was in the foto viewer and at one foto and then clicked at the symbol to rotate left. Then digikam crashed.
When I try to reproduce it, digikamt is crashing everytime directly after that step.
So I typed #gdb digikam into the console, but could not get digikam startet. after the crash the debug window is opening and so i am here now.

I don't have deeper debug knowledge so I can't tell if the crashing is related to the bug report called "Crash on rotate" which was closed by Gilles, because of external program crash.

So I will apreciate it, when someone with deeper knowledge kann analyze the bug and get the info out, if the fault is internal or of an external program.

Thanks to you/ them
Sapuani Teclada

The crash can be reproduced every time.
