Hi, I just upgraded to version 1.0.5 hoping to get rid of a problem that 
made Thunderbird download all mails from time to time. I now see this 
error (below). Does anyone know what it means?

Error: IMAP(user): 
Broken header (uidvalidity = 0, next_uid=10)

Error: IMAP(user): 
/mail2/home/user/.Maildir/.Folders.2005/dovecot-uidlist: Broken header 
(uidvalidity = 0, next_uid=1186)

Mails are stored in userhomedirs that are located on a NFS export.

See below output from dovecote -n

[root at mail dovecot-1.0.5]# /usr/local/sbin/dovecot -n
# 1.0.5: /usr/local/etc/dovecot.conf
