You are using compiled sources. Can you test this patch? The problem here is not reproducible, but the patch could be the solution.

Comment 2 caulier.gilles 2017-06-22 21:43:01 UTC 
digiKam 5.6.0 is now released and available as bundle for Linux, MacOS and Windows.

https://www.digikam.org/news/2017-06-21-5.6.0-release-announcement/

Can you check if problem still exists with this version ?

Thanks in advance

Comment 4 caulier.gilles 2017-07-23 18:27:56 UTC 
New digiKam 5.7.0 are built with current implementation as pre-release bundles:

https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM

Problem still reproducible ?
Comment 5 caulier.gilles 2018-08-17 21:22:53 UTC 
No feedback. Sound like a binary compatibility issue with native package.

This crash is not reproducible with 6.0.0

I close this file
Comment 6 caulier.gilles 2018-08-17 21:24:55 UTC 
Oups,

Maik,

I don't see your patch attached. ou you fell it need to apply to git/master (or perhaps you have already apply it) ?

Gilles
Comment 7 caulier.gilles 2018-08-17 21:27:39 UTC 
Can you reproduce the dysfunction using digiKam 6.0.0 pre-release bundle available here :

https://files.kde.org/digikam/

Comment 8 Maik Qualmann 2018-08-17 21:42:25 UTC 
No, the patch was not applied because I could never reproduce the problem.
