What user/group does dovecot_virtual_delivery run as? Change the stats-writer socket's owner to be that user. For example:

service stats {
  unix_listener stats-writer {
      user = vmail
  }
}

Or alternatively change dovecot_virtual_delivery to use dovecot group.

Looks like this is happening now because in earlier versions the dovecot-lda process wasn't sending any statistics.
