[Evolution] Courier IMAP odd behavior

[Blake Barnett <blake barnett developonline com>]

I'm running evolution 1.0.7 on Debian Sid.  My mail server runs
Courier-imap v1.4.3 w/ssl on Debian woody.

I'm pretty sure this is a known issue, but I can find no solution or
further information from searching the archives.

When I create a new account _sometimes_ it works correctly for a few
minutes but it always reverts to saying "This folder cannot contain
messages" for the INBOX.  I believe that from my testing it appears to
happen when I create a subfolder.  

Also if I set the "Override server supplied folder namespace" to ".",
then I am able to access messages in the INBOX but all the subfolders
disappear.  I am also not able to create subfolders in this state.

I have tried deleting my ~/evolution directory, recreating the account,
removing (purge) and reinstalling evolution.  It does not help.
