Comment 1 Maik Qualmann 2017-12-01 21:43:01 UTC 
DigiKam-4.4.0 is over 3 years old. This version is no longer supported. Please use a current version. If your distribution does not have a more recent version, try the AppImage from https://www.digikam.org or a pre-release version from here https://files.kde.org/digikam/ I close this bug as unmaintained.

Comment 2 caulier.gilles 2017-12-16 10:53:27 UTC 
This crash is not reproducible use current 5.8.0 pre-release bundle available
here :

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

I close this file now. Re-open it if necessary.
