Description

Current version, syncing 2 CalDAV calendars (Nextcloud + SOgo)
I setup a recurring event which repeats forever, yearly, every 4th Saturday of April

This event syncs properly.
If I edit it in Mac Calendar.app (macOS) and do whatever, it seems the event is adjusted to include COUNT=0.
vdirsyncer then will throw an internal error:
COUNT in RRULE must be a positive integer

COUNT=0 should be allowed though for endless events

Research direction

The issue names no file or test. Start by reproducing the CalDAV synchronization with an RRULE containing COUNT=0 and trace where vdirsyncer reports the internal error; done means COUNT=0 is accepted as an endless recurrence and the affected calendar sync completes without that error, with a regression test covering the case.
