Some options for views_plugin_argument_validate_user cannot be saved after "Retool exports to drill down properly"

When saving options for this plugin, i get:

warning: array_filter() [function.array-filter]: The first argument should be an array in /drupal/sites/views3dev/modules/views/modules/user/views_plugin_argument_validate_user.inc on line 56.

This is produced by this function with a extraneous $options parameter:

  function options_submit(&$form, &$form_state, &$options) {
    // filter trash out of the options so we don't store giant unnecessary arrays
    $options['roles'] = array_filter($options['roles']);
  } 

However if this function is removed, "Restrict user based on role" and "Roles" are not saved.

Also, the process_dependency is broken and roles are displayed even if "Restrict user based on role" is unchecked.
