I *think* I figured it out, the mailboxes that were causing the errors each had a file in them named “:,2” since removing those and removing the dovecot-uidlist the problem hasn’t returned.
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
