The primary symptom is that as it downloads messages Mail.app just hangs; no response, the session just freezes. Usually it's when the status bar is saying something akin to "Caching 9 of 506" at which point it stops. The number varies, but it's always in the first couple of dozen. Messages are small, so it's not that it's hanging on a large mail download. I eventually have to forcibly kill Mail.app.
My best guess is that it uses FETCH ENVELOPE, which is somewhat broken in 0.99.8 if some headers (subject, in-reply-to mostly) contain '"' characters. BODY and BODYSTRUCTURE fetches can also break but they're less likely to contain '"' chars.
Try if the included patch fixes. Dovecot may have cached those replies already, so delete all .imap.index* files.
