-- Information about the crash:
- What I was doing when the application crashed:
I have just launched DigiKam

- Custom settings of the application:
I have installed DigiKam, at first launch it asks me some parameters. I have selected the folder of my pictures (a NFS mount) and kept all default options. After that it has crashed and any other launch resulted in a crash.

The crash can be reproduced every time.

It's probably due to the whole qdebug message forwarded by SUSE from user applications to system log. This is completely stupid... 

We have turn around this problem with 7.2.0 release. You can test with pre-version AppImage bundle available here :

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

Comment 2 Maik Qualmann 2021-03-06 20:21:06 UTC 
The crash is not in digiKam. It crashes in a Qt Quick Widget. I suspect your system notifikation widget is crashing here. this is probably a package problem.

Comment 3 Maik Qualmann 2021-03-06 20:35:41 UTC 
I think thread 6 is the cause of the crash and this one belongs to QWebEngine.

Comment 4 caulier.gilles 2021-03-30 06:53:26 UTC 
digiKam 7.2.0 official release is published with more than 360 files closed from bugzilla:

https://www.digikam.org/news/2021-03-22-7.2.0_release_announcement/

Can you reproduce the dysfunction with this version ?

Thanks in advance for your feedback

Hello,

I cannot reproduce with DigiKam 7.2.
Thanks for all!
Comment 6 Maik Qualmann 2021-04-27 17:04:20 UTC 
Thanks for the feedback.
