[Plugin: OpenID] Missing check for $wp_scripts

When signed in with an OpenID, the following error was being displayed at the bottom of the post page:

PHP Fatal error: Call to a member function query() on a non-object in /blog/wp-content/plugins/openid/comments.php on line 182

There was a missing isset($wp_scripts). The code sample below includes my fix and corrects a typo in your comment 😛

/**
 * Print jQuery call for stylizing profile link.
 *
 * @action: comment_form
 **/
function openid_comment_profilelink() {
	global $wp_scripts;
	if ((is_single() || is_comments_popup()) && is_user_openid() && isset($wp_scripts) && $wp_scripts->query('openid')) {
		echo '<script type="text/javascript">stylize_profilelink()</script>';
	}
}

Is there perhaps a more serious problem, in that $wp_scripts isn’t set?
