--- Comment #2 from Erik Quaeghebeur <bugs.kde....@e3q.eu> --- Created attachment 148238 --> https://bugs.kde.org/attachment.cgi?id=148238&action=edit New crash information added by DrKonqi kmail (5.19.3 (21.12.3)) using Qt 5.15.3 - What I was doing when the application crashed: Trying to restart kmail after it had crashed on quitting after it was stuck loading the contents of a folder.
