Access error in Views

PhP error log reveals the following about this bg:

[31-Jul-2008 07:24:09] PHP Fatal error: Cannot access empty property in /Applications/MAMP/htdocs/drupal/sites/default/modules/views/modules/node.views.inc on line 557

which seems to refer to

/**
* Render whatever the data is as a link to the node.
*
* Data should be made XSS safe prior to calling this function.
*/
function render_link($data, $values) {
if (!empty($this->options['link_to_node'])) {
return l($data, "node/" . $values->{$this->aliases['nid']}, array('html' => TRUE));
}
else {
return $data;
}
}

No. No modules concerned with access.

I think this is what you want--my best effort at an export. Perhaps I should have saved it as an attachment. If that's the proper protocol, just tell me, and I'll do better in the future.
