if the Maildir has the file ":,2" in it, you get two errors the first time 
you select that mailbox:

Error: Broken file /<root>/Maildir/.t/dovecot-uidlist line 2: Invalid extended fields: :
Warning: Fixed a duplicate: /<root>/Maildir/.t/cur/:2, -> 1382969744.M379516P28028.msa

but the ":2," remains in the Maildir. The next time the mailbox changes, 
e.g after "touch /<root>/Maildir/.t/cur", you only get the first error.

Actually such file should never exist in a Maildir and is most likly not 
created by Dovecot itself, but for robustness Dovecot could rename such 
file into some sane name. Tested with

# 2.2.5 (9531ec8afe8b): /usr/local/dovecot-2.2.5/etc/dovecot/dovecot.conf

Thanks,
