well, the bug is here:

 zope/app/component/browser/registration.py

    @form.action(_("Register"))
    def register(self, action, data):
        sm = component.getSiteManager(self.context)

in that case 'sm' and 'context' are the same.

I've filed a bug at:
http://www.zope.org/Collectors/Zope3-dev/597

a solution would be to get the site manager on the parent folder, eg.

       if sm == context:
            sm = component.getSiteManager(getParent(context))

   ...
