[Dovecot] 1.0.10 - Cached message offset lost

[Anton Yuzhaninov]

After upgrading from dovecot-1.0.7 to dovecot-1.0.10 any time when I delete message in logs appeared messages 
like:

Feb 16 23:54:05 mail-chaos dovecot: IMAP(citrin): Cached message offset lost for seq 2 in mbox file 
/spool/mail/citrin.ru/citrin/Trash
Feb 16 23:54:05 mail-chaos dovecot: IMAP(citrin): copy -> Trash: uid=3589, 
msgid=<E1JHT55-0009fX-3E at spray.anyhost.ru>

Removing the index files does not help.

When new mail delivered same messages written to the log by deliver.
