[Dovecot] Upgraded from 0.99 to 1.0 stable on FC3

Hi

I upgraded to 1.0 stable and saw this in the maillog

UIDs broken with partial sync in mbox file /var/spool/mail/thejohns_brian

i am using mbox files with default_mail_env = mbox:/var/spool/mail/%u

Is this a problem that i should worry about?
