dovecot - Aug 2009 - autocreate plugin fails to subscribe mailbox in public namespace

Hi,

I'm one step away from replacing a 7 years old qmail/uw-imapd setup
with some state of the art soft- and hardware. We got migration
scripts and test almost done - just one thing that keeps failing:

The autocreate plugin is supposed to subscribe new users to different
mailboxes, one of them being in namespace "Public." - this
subscription to "Public.announcements" fails.

Below is a dovecot -n - and no, there are no error messages in the
logs.

BTW: If anybody is interested, I could provide load and usage
statistics of our old and new software once step 1 of our migration
(new hardware is step 2) is done. Only ~1000 users, but still...

Fixed: http://hg.dovecot.org/dovecot-1.2/rev/85e39b7710ee
> # 1.2.2: /etc/dovecot/dovecot.conf
There was one maildir performance bug in v1.2.2, I'd use v1.2.3 or at
least apply the fix: http://hg.dovecot.org/dovecot-1.2/rev/25c9df95fda6
