Comment 1 caulier.gilles 2018-02-26 13:23:41 UTC 
Problem is reproducible with digiKam appimage linux bundle 5.9.0 pre-release ?

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

To run showfoto, look bundle option on CLI :

Comment 2 caulier.gilles 2018-08-17 21:27:18 UTC 
Can you reproduce the dysfunction using digiKam 6.0.0 pre-release bundle available here :

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

Comment 3 caulier.gilles 2018-12-31 11:51:33 UTC 
Can you reproduce the dysfunction using the last digiKam 6.0.0-beta3 just
released ?

Comment 4 caulier.gilles 2019-03-07 05:21:16 UTC 
Good news,

After 2 weeks of works, the pre-release 6.1.0 bundles are now reconstructed from scratch with:

- All OpenCV options for CUDA, OPenMP, and OPenCL disabled to prevent crashes
in face management.
- A large upgrade of Qt5 from 5.9.7 to 5.11.3.
- An upgrade to KF5 5.55.
- An upgrade to Ffmpeg 3.3.9
- The fontconfig/freetype integration in the bundle to reduce system
dependencies

Files can be downloaded here :

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

Please test and report.

Comment 5 Maik Qualmann 2019-12-14 15:46:42 UTC 
This crash was now been fixed. Before we go in the QMutex, we check whether the loading has been canceled because digiKam / showFoto is terminated.
