[Zend_Application] Incorrect number of Arguments in calling registerNamespace

[LuCarD]

In Zend_Application the registerNameSpace is called from the setAutoloaderNamespaces Method.

public function setAutoloaderNamespaces(array $namespaces)   
 {
    $autoloader = $this->getAutoloader();

    foreach ($namespaces as $namespace) {
        $autoloader->registerNamespace($namespace);
    }

    return $this;
}

The autoloader ( Zend\Loader\StandardAutoloader ) is expecting an extra directory argument.
/**
* Register a namespace/directory pair
*
* @param string $namespace
* @param string $directory
* @return StandardAutoloader
*/
public function registerNamespace($namespace, $directory)
