[Dovecot] how to store flags \Seen into read-only mailbox?

[seriv at parkheights.dyndns.org]

This problem is apparently about changeset http://hg.dovecot.org/dovecot-1.1/rev/eec74a6ad62e.
This change makes dovecot behaviour different from what is described in wiki, about sharing and making private /Seen flags, 
see http://wiki.dovecot.org/SharedMailboxes?highlight=(flags are shared or private)
When I've tried to revert it, first time with my client it worked perfectly.
But then clients were not able to open any mail folders, and imap processes were dying.
