Next time, I suggest you paste the error traceback, because that's way 
more informative than a code snippet from Five that everybody can lookup 
by himself. Right now I had to guess what component it failed to lookup...

It's registered in zope.app/menus.zcml. This file is probably not 
available in Zope 2 (anymore):

   <menu
       id="zope.app.container.add"
       title="Add"
       description="Menu for objects to be added according to
                    containment constraints"
       interface="zope.app.publisher.interfaces.browser.AddMenu"
       />

add_content is old and no longer used in Zope 3.

*Sigh*. This is *exactly* why I want to get rid of all of this useless 
code duplication in Five.

For now I suggest you guys register zope.app.container.add yourself. Or, 
perhaps you register a variant and also regsiter your own adding view 
that refers to your variant.
