Kalendar crashed after I right-clicked on an event. I couldn't reproduce after restarting the program.

The crash does not seem to be reproducible.

Comment 2 Riccardo Robecchi 2023-01-31 14:46:44 UTC

The crash is actually always reproducible, it's the conditions that are different: Kalendar crashes when an event is dragged and then dropped on the same day. It doesn't happen when it is dropped on a different day.
