dovecot - May 2010 - Dovecot 2.0.beta5: dovecot-uidlist: Duplicate file entry at line X

Hi,

I'm using dovecot 2.0.beta5 (IMAP and LMTP+sieve) and I'm getting lots
of errors like this:

Warning: /data/mail/4567/Maildir/dovecot-uidlist: Duplicate file entry
at line 3: 1274182284.M635158P16414.mail,S=767,W=785:2,S (uid 5 -> 16)

All data is stored on local disk (ext3, no NFS!). As this is a fresh
installation of dovecot I do not know if older versions work better.
One user complained about loosing email from inbox but I guess that's
probably a user error :)

I think that the error might be related to deliveries via LMTP as this
(new) functionality has not been tested extensivly (?)

Regards,
Chris

Update (I really can't believe it but it seems to be true): These
errors disappear if the user installs a sieve filter file. It doesn't
matter if the filter is simple (e.g. just "keep;") or complex (many
rules and fileinto subdirs).
