[Evolution] Cannot delete caldev, exchange calendars

["A.G." <prothonotar tarnation dyndns org>]

I've got an old exchange calendar (2 actually) that still shows up under
an exchange account that has long since been disabled. Yet I cannot get
the calendar to be removed in evo. I've even tried removing the
evolution-connector rpm, to no avail.

What's really killing me right now though is that I was fiddling with
seeing if google's calendar would work via CalDAV. Well, it doesn't, but
now I can't remove it. I've tried removing it with the CalDAV plugin
enabled and disabled, to no avail. Yet whenever I right-click on the
calendar to try to remove it, I get immediately prompted for the
password. No matter what I do though, it never gets removed. 

So the calendar is there, but unchecked. I could live with this by
itself, but its causing problems with meeting notices that people send
me. Whenever I select a meeting notice, I am prompted for the password
for this disabled, never working, unremovable CalDAV calendar. It blocks
me from actually adding a meeting notice to my enabled "On This
Computer" calendar which has been working fine for me for a long time.

Is there some workaround, or even some file I can hand-edit to fix this
situation? This has reached a critical blocker stage for me and I'm
happy to fill a bug report if one doesn't already exist, but I'd like to
be able to accept appointments in the meantime. :(

Thanks in advance.
