In "Products.CMFCore.DynamicType.DynamicType.__before_publishing_traverse"
I see code like:

    def __before_publishing_traverse__(self, arg1, arg2=None):
        """ Pre-traversal hook.
        """
        # XXX hack around a bug(?) in BeforeTraverse.MultiHook
        REQUEST = arg2 or arg1

Apparently, your problem has been observerd by others and they
worked around it this way.
