ack, sorry ... just click on 'Time-Tracking', its the first error at the
top of hte page ... had one person comment about it to me on the demo
site, as he's seeing the same thing and figured it was an error on his
side ... it may still be 'operator error', but i can't seem to find where
...

The function in Form.php is:

    function &addVariable($humanName, $varName, &$type, $required,
                          $readonly = false, $description = null)
    {
        $var = new Horde_Form_Variable($humanName, $varName, $type,
                                         $required, $readonly, $description);
        if ($var->getTypeName() == 'enum' &&
            count($var->getValues()) == 1) {
            $vals = array_keys($var->getValues());
            $this->_vars->addVar($var->varName, $vals[0]);
        }
        $idx = array_push($this->_variables, $var);
        return $this->_variables[$idx - 1];
    }
