Comment 1 caulier.gilles 2012-12-04 09:13:23 UTC 
As i suppose that you modify image in editor, trace is about TimeLine tool. I suspect a corrupted backtrace, not relevant of real problem.

Please try to reproduce the problem using GDB to get a better backtrace :

Comment 2 Unknown 2012-12-04 09:26:36 UTC 
Dear Gilles,
Yes, I've modified in editor and used the KDE bug tracer to report the problem (I installed the digikam-dbg as required). 
After that, I did use the editor without problems. If I see again similar issues and can reproduce I'll use GDB. 

cheers,
Francesco

digikam (3.1.0) on KDE Platform 4.10.2 using Qt 4.8.4

- What I was doing when the application crashed:

I was trying to figure out meta data editing. Went to next photo which closed the 'edited' photo. Crashed occurred. I believe this is very similar or the same as previously reported occurances.

Hi,

I've tried digiKam 4.12.0 on opensuse Tumbleweed (on plasma5/KF5) and it works.
Thanks for fixing the bug.

I forgot to test when you asked in June, sorry.
