Notice: Undefined property: stdClass::$nid in fivestar_views_value_display_handler()

I get this notice message on view that shows average rating for current node.

Notice: Undefined property: stdClass::$nid in fivestar_views_value_display_handler() (line 1398 of ... \www\d7_test\sites\all\modules\fivestar\fivestar.module).

Some background:
I don't like the default method to display average score of comments proposed in http://drupal.org/node/234681 so I managed to attach view to node (using EVA module) which shows average score for current node.
I don't know if this is good or bad but it's better than hardcoding template file :)

Solution (at least in my case):
change

    if (isset($columns->node_type)) {
      $stars = variable_get('fivestar_stars_'. $columns->node_type, 5);
    }
    else {
      $node_type = db_query("SELECT type FROM {node} WHERE nid = :nid", array(':nid' => $columns->nid))->fetchField();
      $stars = variable_get('fivestar_stars_'. (!isset($node_type) ? 'default' : $node_type), 5);
    }

in fivestar_views_value_display_handler() function to

    if (isset($columns->node_type)) {
      $stars = variable_get('fivestar_stars_'. $columns->node_type, 5);
    }
    else {
      if (isset($columns->nid)) {
        $node_type = db_query("SELECT type FROM {node} WHERE nid = :nid", array(':nid' => $columns->nid))->fetchField();
      }
      $stars = variable_get('fivestar_stars_'. (!isset($node_type) ? 'default' : $node_type), 5);
    }

In my case $column variable has value
stdClass Object ( [votingapi_cache_node_percent_rating_average_value] => 66.6667 [node_created] => 1304006434 )
