[Dovecot] pop3 not working properly in 1.0.r19

[Charlie Root]

Hi,

I often see this message:
Feb  1 14:42:44 vlk dovecot: POP3(obec at nizkov.cz): Mailbox init failed top=0/0,
retr=0/0, del=0/0, size=0
Feb  1 14:42:44 vlk dovecot: POP3(obec at nizkov.cz): mbox sync: UID inserted in
the middle of mailbox /var/mail/obec at nizkov.cz (68386 > 68346, seq=2, idx_msgs=3)

this is on FreeBSD at i386 runnin 1.0.r19 (but I have seen this with all versions
of 1.0.x), filesystem in use is UFS (ie. local filesystem). THe mailing client
in question seems to be outlook express. I can provide the mbox in question.

locking method is 
#lock_method = flock

and the dovecot was compiled with kqueue

thnx
