[fw-db] Possible bug in Zend_Db_Select::assemble function BA7-899

Hi,

I think that the Zend_Db_Select::assemble method is bugy.
I would expected something like:

/**
* Converts this object to an SQL SELECT string.
*
* @return string This object as a SELECT string.
*/
public function assemble()
{
$sql = self::SQL_SELECT;
foreach (array_keys($this->_parts) as $part) {
$method = '_render' . ucfirst($part);
if (method_exists($this, $method)) {
$sql = $this->$method($sql);
}
}
return $sql;
}

If so I can create un bug report. With the atteched patch

Thanks
