New crash information added by DrKonqi

akonadiserver (5.14.2 (20.04.2)) using Qt 5.12.7

- What I was doing when the application crashed:

I started Kmail, then akonadi crashed. When just starting akonadi (through "akonadictl start") it doesn't crash, but immediately does so when Kmail is started.
