"Display node comments" is not displaying comments

My understanding is that by selecting "Display node comments" in the "Row style options", the view will display the comments associated with each node. When I select this option however, no comments are displayed. When I view the html source of the view I see that <div id="comments"></div> </div>is printed under each node, but no comment information is being printed. I tried this on a clean install with the same results.

I am using the following settings:
Node View type
Style: Unformatted
Row style: Node
Row style options: Display node comments

SQL Query:

SELECT node.nid AS nid FROM node node 

Exported View:

<?php
$view = new view;
$view->name = 'node_plus_comments';
$view->description = 'Lists nodes plus their comments';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('access', array(
  'type' => 'none',
));
$handler->override_option('row_plugin', 'node');
$handler->override_option('row_options', array(
  'teaser' => 0,
  'links' => 0,
  'comments' => 1,
));
$handler = $view->new_display('page', 'Page', 'page_1');
$handler->override_option('path', 'nc');
$handler->override_option('menu', array(
  'type' => 'none',
  'title' => '',
  'weight' => 0,
  'name' => 'navigation',
));
$handler->override_option('tab_options', array(
  'type' => 'none',
  'title' => '',
  'weight' => 0,
));
?>
