"This bug still persists. In particular, I just (after the new version was applied) clicked on an email from Person X, and Thunderbird displayed an email from Person Y that I had just replied to. Note that the email from Y was not adjacent to the one from X (at least, in the temporal ordering)."
Is it possible that this email was downloaded using Dovecot 0.99 and Thunderbird's cache was already broken for it? You could tell him to delete TB's cache and see if it still happens.
Another thing that comes to my mind is that how do you deliver mails to maildirs? If the filenames aren't truly unique something like this could happen. Although Dovecot detects that as long as you haven't disabled its index files.
Anything in logs?
