Summary: Call to undefined method XmlContent::setAttr()

Initial Comment:
Seeing this in my logs on www.hollenback.net:

[Sat Mar 03 06:23:13 2012] [error] [client 173.245.56.228] PHP Fatal error:  Call to undefined method XmlContent::setAttr() in /var/www/phpwiki/lib/plugin/RecentChanges.php on line 628

that's happening in fuction DiffLink:

   function diffLink ($rev) {
        $linkurl = parent::diffLink($rev);
        $linkurl->setAttr('target', '_content');  // this line
        $linkurl->setAttr('rel', 'nofollow');
        // FIXME: Smelly hack to get smaller diff buttons in sidebar
        $linkurl = new RawXML(str_replace('<img ', '<img style="height:2ex" ', asXML($linkurl)));
        return $linkurl;
    }

Can someone help me troubleshoot this?  Thanks.
