Please describe the problem:
I created a meeting on my calendar and wanted to change it from a single shot to
a recurrance meeting.  Selected the meeting, clicked on the recurrance, told it
to make it recur X times.  This actually creates a new appointment in my
calendar with the recurrance rather than modifying the old one.  No biggie, just
delete the old one - nope, it deletes the new recurring one.  May be related to
severe difficulties I have in modifying recurring appointments and adding in
exceptions (i.e. it doesn't work and usually kills that appointment).

Steps to reproduce:
1. create one shot appointment
2. modify to recurring appointment
3. try to delete original one shot



Actual results:
A new appointment is created and the original one shot still appears.  Deleting
the one shot deletes the recurring appointment.

Expected results:
the one shot appointment would be changed to a recurring appointment.  Step 3
above would be unnescessary because there wouldn't be an extra appointment on my
calendar.

Does this happen every time?
No, it's very erratic.

Other information:
Actually, now I notice when I restarted evolution, both sets of appointments are
gone but the modification works.  Frustrating.
