I am not sure where to report this. It is an issue with python-dateutil module, more than khal, but nonetheless I report here (and radicale) in search for help. When trying to sync a calendar built from khal to radicale I get

Traceback (most recent call last):

ValueError: unsupported DTSTART parm: VALUE=DATE-TIME

Which is due to rrule.py not wanting any parameter to DTSTART. Can I do something about this, or where should be the correct place to report it?
