[Dovecot] dovecot deliver errors

[Andrew Garner]

I think someone else mentioned this problem earlier on the list, and
I've recently started seeing the following error show up:

file index-transaction.c: line 54 (index_transaction_finish_rollback):
assertion failed: (t->mail_ref_count == 0)

With beta11 I started running into this problem (using postfix's
smtp-source messages):
