[Dovecot] question about snarf plugin in dovecot 2

I was hoping to get a quick resolution to this; hopefully something I'm 
doing wrong.  I'm hoping to put dovecot in production tonight. ;-)

I thought I was getting closer, but...

 From looking at the logs, I see that other plugins are loaded in the 
imap service (quotas for example).  So, I added 'snarf' to my mail plugins.

protocol imap {
  ...
  mail_plugins = $mail_plugins imap_quota snarf
  ...
}

Once I do that, I see that the plugin does load.  And now it no longer 
creates an ~/mbox if it doesn't first exist.  Then again, it now panics, 
so perhaps that is happening before getting to the point of creating the 
~/mbox file.  Since the panic is happening just after reference to 
.../var/run/dovecot/empty, I'm wondering if it has something to do with 
that directory.
