repeating calendar entry doubles up

Binary package hint: evolution

In evolution, I wish to enter several identical appointments for the month, which do not fall cleanly on a particular day of the week: the exceptions for missing days I note using the exceptions entry method provided, so that they do not appear, and then I copy an existing appointment to the non-regular days which do not fit the regular meeting method that evolution offers. However, the paste operation hangs the calendar, and it either crashes on its own or I force close it.

When I now look at my appointments in the time/date calendar in the GNOME panel (top right in Ubuntu Hardy default) I see that the copied appointments are in fact there, *but* the appointment appears twice (e.g., two rows saying the same thing). This double-appointment does not manifest when I open the actual calendar full-screen, nor do I see a way to edit away the double entry.

I also note that when I change a regular appointment from N entries to N-1 entries the calendar hangs and the appointment number is not changed, so I need to remove the individual appointment manually using the right-mouse menu (delete current appointment instance).

Regards,
  Gernot Hassenpflug
