[Dovecot] Reproducible duplicate messages bug with Mail.app+Dovecot

I am not sure if this is a Mail.app bug or a dovecot bug. I can
reproduce it 100% of the time using dovecot and Mail.app. I cannot
reproduce it with other imap clients, which at first made me think it
was Mail.app, but then I tried Mail.app with other imap servers and
couldn't reproduce it either, so it's definitely the combination of
the two. So I thought I'd try you guys first before submitting a
bug to Apple.
The problem: If I move multiple messages (set "A") from one imap
folder to another, then delete those messages, and then move another
set into that same folder (set "B"), then all the messages in set B
show up as duplicates until I relaunch Mail.app.
Server: Dovecot 1.0rc22 using Maildir on FreeBSD 6.1
Client: Mail.app 2.1 on OS X 10.4.8
Steps to reproduce: (these steps involve trashing messages, so it's
best to test this on email you are going to toss anyway)
1) Create a new imap folder (let's say "bar")
2) Drag more than one message (let's say 3 or 4) from existing imap
folder "foo" to new folder "bar".
3) Click on new folder "bar" and see messages in there.
4) Select messages and delete them (Delete key). Messages are gone
5) Go back to original folder "foo" and drag a few more messages into
new folder "bar"
6) Click on bar.
7) You will notice that all the second set of messages show up twice.
Relaunching Mail.app at this point makes the problem disappear. I'm
guessing this has something to do with the deleted messages from Set
A being purged until the close of imap connection.
Any help narrowing this down would be appreciated.
