-- Information about the crash:
- What I was doing when the application crashed:
I was restarting akonadi using akonadiconsole. The reason is that I am having serious trouble with akonadi after the upgrade from 19.04.3 to 19.08.3.

-- Backtrace:
Application: KOrganizer herinneringsdaemon (korgac), signal: Segmentation fault
