[Dovecot] dovecot 1.1alpha6 deliver+quota bugs

I was playing around with dovecot-1.1 and maildir++ quotas, and ran
into a reproducible error with indexing.    This only seems to be a
problem for new maildirs.   If I send a message without the quota
plugin on, and  "seed" the index/control files, future deliveries with
the quota plugin seem to succeed without errors.


Version: 1.1alpha6

Here's the deliver-log from a "fresh" Maildir (just
~/Maildir/{cur,new,tmp}):

Turning off the quota plugin will allow the delivery to succeed:

Turning quota back on has a temporary complaint about uidvalidity:

But then it's pretty happy:

But once I hit the quota limit, I get an assertion failure:

Mailbox list indexes were supposed to be disabled by default, since
they're buggy. I didn't think that they'd still be enabled in
deliver.
This disables them completely for now:
