[Dovecot] Ximian Evolution Issue

Hi

This may be a problem with Dovecot and it may be a problem with Evolution, I'm trying to narrow it down. I'm using Evolution 2.0.2 on Fedora Core 3 x86_64 to connect over SSL to Dovecot 0.99.11 on Debian testing (Sarge) on an i686 using Maildir for the mail store.
Specifically, when I open a folder with more than a few dozen messages in it I get the following error (with the carroted fields populated):

Error while Opening folder imap://<username>@<mailserver>/<folder>.

Incomplete server response: no information provided for message <message number>.

Thanks for any leads on this! Adam
