dovecot - Nov 2007 - Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged

After updating Dovecot, one of my servers keep spamming these errors in 
the log:

dovecot: Nov 03 14:14:18 Error: POP3(foo at bar.com): Getting size of 
message UID=4402 failed
dovecot: Nov 03 14:14:18 Error: POP3(foo at bar.com): Getting size of 
message UID=4402 failed
dovecot: Nov 03 14:14:18 Error: POP3(foo at bar.com): Couldn't init INBOX: 
Can't sync mailbox: Messages keep getting expunged

The funny thing is the mailbox is empty, there are no mails in the 
folder that should be needed to be parsed

It was perfectly fine before I updated, and the permissions on the 
folder is correct. It only affects some mailboxes as well.

Any ideas?

So cur/ and new/ directories are empty? What does dovecot-uidlist's 4402
entry contain?

I think it's related to the change in the cache files.

I had a customer who couldn't see any mails in their inbox, what so ever -
there were plenty of files in the cur/ folder though.

After a bit of "wtf is going on here", I removed the dovecot* files in
the
maildir, and then it worked fine.

I think I will take the consequence and simply make a script to nuke all
dovecot cache files in my maildir folders.
