[Dovecot] dirsize quotas crashing 1.0.rc19

[Dean Brooks]

Hi,

I've been trying to get dirsize quotas to work properly with 1.0rc19
and Dovecot consistently crashes when attempting to do file copies
once a user is over quota.

Dovecot works fine for us for regular mbox based IMAP, but as soon as I
add the following two entries in their respective locations in dovecot.conf:

   mail_plugins = quota imap_quota     (in the imap{} section)
   quota = dirsize:storage=2000        (in the plugin{} section)

If a user goes over quota, and they attempt to copy a file to a folder
via IMAP, all I get is this:

 dovecot: [ID 684838 mail.error] child 20868 (imap) killed with signal 10

Is anyone successfully using dirsize:storage quotas with 1.0rc19?  If
so, can someone else verify if they see crashes like this?

As soon as I remove the quota plugin, the crashes go away and all is
good, so there's obviously some sort of problem in the quota plugin.
