I was moving a single occurance of a recurring event from one day to another. I tried a couple of times and it didn't seem to update. I moved to another application and about 15-30 seconds later, Kalendar crashed. 

I have the versoin of Kaleandar from KDE backports

The reporter is unsure if this crash is reproducible.
