Bug when empty results

Hi,
I have a view with relationships and contextual filters.
When the view has no results, the view crashes due to Views Tree.
Doing some debugging I was able to pinpoint to this part of the code:

$items[] = $rows[$i] . call_user_func(__FUNCTION__, $variables);

(views_tree.module line 132)

After a bit of investigation it seems this is due to the assignment above $variables['parent'] = $record->views_tree_main; assuming views_tree_main is filled in, when it is in fact 0.

By adding a check to that variable it's fixed.

So changing

  foreach ($result as $i => $record) {
    if ($record->views_tree_parent == $parent) {
      $variables['parent'] = $record->views_tree_main;
      $items[] = $rows[$i] . call_user_func(__FUNCTION__, $variables);
    }
  }

to

  foreach ($result as $i => $record) {
    if (!empty($record->views_tree_main) && $record->views_tree_parent == $parent) {
      $variables['parent'] = $record->views_tree_main;
      $items[] = $rows[$i] . call_user_func(__FUNCTION__, $variables);
    }
  }
