[Dovecot] local seen flags with shared mailboxes

Hello all,

after recent upgrade from 2.0.5 to 2.0.8 it seems that local seen flags for mails reside in shared mailboxes doesn´t work anymore.

Before the upgrade I had read mails with account #1. Account #2 (who has access via acl) saw the mails still as unread. Now, no matter who read the mails, the other account see the same flags, immediately.

I read the related wiki pages again and tried to find any configuration error, unfortunately without much success. I´ve attached output from "doveconf -n" and a debug logfile.

Thanks a lot! Tim
