I'll add that Lamiral's imapsync utility performs the sync operation for 
this 'problem mailbox' just fine:

server:~# imapsync --exclude=.procmailrc --exclude=vacation.msg 
--exclude=.bash_history --exclude=remote_pinerc --host1 
panda-imap-server.contoso.com --user1 username-dc --host2 localhost 
--user2 username*master
