Oops - this made me loose all my action providers.
This seems to work a bit better:

    def addActionProvider( self, provider_name ):
        """ add the name of a new action provider """
        ap =3D self.action_providers
        if type(ap) is not type([]) and type(ap) is not type(()):
            ap =3D []
        if hasattr( self, provider_name ) \
          and not provider_name in ap:
            ap.append(provider_name)
            self.action_providers =3D ap
