Support RDATE;VALUE=PERIOD

[geier]

currently blocked by missing support for this in icalendar, see collective/icalendar#156

[geier]

From here it looks like a different issue. Please open a new one and post more of the ics file (feel free to remove any private information) as I cannot currently reproduce the error with the part you pasted here.

This would be good to have. Here is a curtailed entry that I imported to khal, but doesn't display in khal:

I should mention that this happened when a previous periodic event was edited to move one of the events two weeks forward.

The icalendar issue is closed so this one might be resolved.
