Comment 1 Nicolas Fella 2021-11-30 17:11:23 UTC

This is not specific to Akonadi. Currently all applications crash when the compositor restarts. This will eventually get fixed in Qt

Comment 2 Alexandre Pereira 2022-02-15 17:12:07 UTC

Created attachment 146782 [details]
New crash information added by DrKonqi

akonadiserver (5.19.2 (21.12.2)) using Qt 5.15.2

- What I was doing when the application crashed:

Kwin wayland crashed, causing akonadi to crash.

In my case, akonadi was the only app that crashed with dr konqui report.

Just submitting, in case crash report info is usefull.
