Please describe the problem:
I send out a meeting request (via the Exchange connector) to a mailing list.  As a result, I get many acceptance emails from people who were not in the original attendees list for the meeting.

When I click the "Update Attendee Status" button for those acceptances, I get a dialog telling me that this person was not on the attendee list, and do I want to add them?

I say yes and it seems to work... except that when I go look at the meeting those people are NOT listed as attendees and I can't find anywhere that does list them.

Steps to reproduce:
1. Send a meeting request
2. Have someone who was NOT on the original attendees list accept the request
3. When you get the accept email back, click "Update Attendee Status"
4. Agree to have them added to the attendee list
5. Go back to the calendar and look at the list of attendees



Actual results:
The extra attendee is not listed.

Expected results:
The extra attendee has been added to the list.

Does this happen every time?
Yes.

Other information:
I'm actually using SVN versions of libsoup, gtkhtml, e-d-s, evo, evo-exchange, and evo-webcal from the gnome-2-20 branch, as of late Sep 17 2007.  But, there's no version for 2.11/2.12 in the version list for the Evo Exchange package.
