[Dovecot] mail-cache-transaction.c error

[F. Even]

The below error is when I check the account from Squirrelmail.  In 
sqmail, the error it reports is this:

ERROR : Connection dropped by imap-server.
Query: FETCH 1:* (FLAGS UID RFC822.SIZE BODY.PEEK[HEADER.FIELDS (Date To 
Cc From Subject X-Priority Content-Type)])

....yet when I check the account from Thunderbird, all is well.

Don't know if that helps or confuses even more.

Any ideas?  Thanks.
