[Zope] Zope 2.2 under Debian (Woody) broken?

Hello, I installed zope 2.2.0-1 from the Debian (Woody) distribution. No problems are reported during the installation but when I try to access http://localhost:9673/ I get the following error: Zope Error Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: unexpected keyword argument: validated_hook The same happens when I try to access the management menus. Is the Woody package broken? Any ideas? Thank you, -- Pedro
