Error with recurring all-day dates

Created by: HerHde

When I'm trying to parse a file which has recurring full-day events the following error occurs:

Traceback (most recent call last):
  File "ical2mail.py", line 260, in <module>
    main()
  File "ical2mail.py", line 247, in main
    events += parse_ics(url)
  File "ical2mail.py", line 101, in parse_ics
    for dtstart_rec in rule.between(DATE_MIN - timedelta(microseconds=1), DATE_MAX):
  File "/[...]/ical2mail/venv/lib/python3.6/site-packages/dateutil/rrule.py", line 290, in between
    for i in gen:
  File "/[...]/ical2mail/venv/lib/python3.6/site-packages/dateutil/rrule.py", line 861, in _iter
    if until and res > until:
TypeError: can't compare offset-naive and offset-aware datetimes

It may be related to dateutil/dateutil#348, but further investigation is necessary.
