Comment 6 for bug 79785

Some of the problems listed below have been solved.
Here is the updated list:

1) Empty lines in calendar file (maybe not a bug)
2) KOrganizer does not deal with DURATION well, it seems to parse it but
   not save it back (http://bugs.kde.org/show_bug.cgi?id=92255) (showstopper)
3) Problems with parsing recurrent events:
  a) when weekly recurrence is specified through the Web interface, KOrganizer
     does not show the event at all.
  b) yearly recurrence is not recognized by KOrganizer (it probably expects
     BYMONTH and BYMONTHDAY to be explicitly specified)

All would be fine and dandy if not for 2), which is a KOrganizer bug (possibly
in some iCalendar processing library) and would require substantial effort to
be fixed.
