[Dovecot] Broken files?

[LuKreme]

Getting a lot of these error for two specific mailboxes. They repeat many times a day, usually within less than 5 minutes.

mail dovecot: imap(kremels): Error: Broken file /home/kremels/Maildir/.zz.x-tech.2010/dovecot-uidlist line 2: Invalid extended fields: :

 $ cat .zz.x-tech.2010/dovecot-uidlist 
3 V1263241007 N56581 G11fe2118db236952f984010021d1a38d

OI tried deleting the files that generated the errors, but they were recreated and the errors returned.

(I’m using dovecot2 and Maildir)
