abusive call to subform_element_submit

In nodeprofile_user('insert') :

if ($types = nodeprofile_get_settings('register')) {
  $new_account = $account; //this will be used on nodeapi op submit to set the correct author uid
  subform_element_submit();
}

nodeprofile_get_settings('register') might be something like array('type1' => 0).
meaning you should probably array_filter it before testing it has values
