Creating node with drupalCreateNode() does not create proper teaser

If I create a node with drupalCreateNode(array('body' => 'Test Data goes here')), the generated node does get a body of 'Test Data goes here', but it gets a teaser of the result of $this->randomName(32).

This is because on line 106 of drupal_web_test_case.php, the code creates a default teaser based on the default node, but it doesn't create a teaser based on the settings node. Fix seems simple, and will attempt to deliver a patch once I am back in Denver with stable internet.
