ad 1: I can confirm that the diary entry, that icalendar.el creates, is
      wrong.

      Expected result is
      - a monthly recurring event *on the first wednesday* of each
        month,
      - starting on 2015-12-2,
      - but not on 2016-06-01, 2016-03-02, 2016-02-03, 2016-04-05,
        2016-01-06
      - from 12:46 to 16:00

      Actual result is
      - a monthly recurring event *on every 2nd day* of each month,
      - starting on 2015-12-2,
      - but not on 2016-06-01, 2016-03-02, 2016-02-03, 2016-04-05,
        2016-01-06
      - from 12:46 to 16:00

      (Actually the result that you provided does not contain the time
      spec.  I presume that it got lost when you pasted it into the bug
      report.  By the way: next time please be a little more specific
      when claiming something is wrong -- thanks!)

ad 2: Cyclic import/export works only for simple diary and icalendar
      entries.  This is known, but unfortunately it is not documented in
      the manual.  (There are some remarks in the source file, however!)

I shall see to these issues.  Thanks for pointing out.
