Comment 1 caulier.gilles 2020-08-16 05:36:26 UTC 
It crash in qDebug message handling from Qt. Your system probably dispatch user space application traces to log files.

This problem have been fixed in last stable digiKam 7.0.0.

Comment 2 Maik Qualmann 2021-02-06 21:31:04 UTC 
The problem cannot be reproduced in digiKam-7.2.0-RC. We have added checks in the album models that the requested QModelIndex is valid. I close the bug.
