I didn't change any defaults regarding dict.

service dict {
  unix_listener dict {
    group = vmail
    mode = 0600
    user = vmail
  }
}

imap-login and pop3-login have "service_count = 0" , but the protocol
directives only have "mail_plugins" set, e.g.:

protocol imap {
  mail_plugins = $mail_plugins imap_quota
}

The patch didn't seem to make a difference. I'm still seeing the error.

If you have any ideas on debugging I'm open to trying them. Dovecot
2.0.1 running on CentOS release 4.8 (Final) i386. MySQL AB's
devel/client/shared rpms, 4.1.22. I can insert some logging probes (or
whatever you like) if you give me pointers on how and where.
