Comment 1 Bug Janitor Service 2023-04-26 17:38:21 UTC 
A possibly relevant merge request was started @ https://invent.kde.org/pim/akonadi/-/merge_requests/136
Comment 2 Carl Schwan 2023-04-26 18:03:20 UTC 
Hi, the crash is caused by akonadi being unable to open the database. Unfortunately akonadi will crash when trying to generate debug information. I created a merge requests making it not crash anymore, but this doesn't fix the root bug that the database couldn't be opened.

If this is reproducible, could you run akonadictl start? And paste the debug output here?
Comment 3 Amaury De Ganseman 2023-04-26 18:11:14 UTC 
Hello,

Don't now why but after restart I can't reproduce the bug...So may be OpenSuSE related....

Git commit 05db7d03baae46513cd6735ec2c3f28733145b0a by Carl Schwan.
Committed on 26/04/2023 at 18:14.
Pushed by carlschwan into branch 'master'.

Avoid crashing before priting debug output when setting up db

Calling debugLastDbError requires the database to be already setup
as it is using the akonadi tracer. So using it to debug why the database
didn't open doesn't work.
