Undefined property: stdClass::$language in pathauto_form_node_form_alter()

Was at Drupal 7.8 now at 7.9 with same results. I'm am getting the following notice in logs on all pages with embedded custom cck forms:

Notice: Undefined property: stdClass::$language in pathauto_form_node_form_alter() (line 427 of /home/my_server/mysite.com/sites/all/modules/pathauto/pathauto.module).

Embedding form in block using:

<?php
$node = new stdClass();
$node->type = 'sidebar_form';
module_load_include('inc', 'node', 'node.pages'); 
$myform = drupal_get_form('sidebar_form_node_form', $node);
$output = render($myform);
print $output;
?>

Hiding unwanted form items using:

function mytheme_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'sidebar_form_node_form') {
		hide($form['menu']);
		hide($form['author']);
		hide($form['options']);
                hide($form['revision_information']);
		hide($form['metatags']);
		hide($form['xmlsitemap']);
		hide($form['path']);
		hide($form['comment_settings']);
		hide($form['title']);

  }
}

Thank you for your time.
