This method added to DataManagers.py seems to fix it.

    def _PropertySheetsFor(self, client):
        """Return a (possibly empty) list of PropertySheet objects for
client"""
        # Note: this could include duplicate sheets if persistent sheets
        # are defined by more than one provider!
        sheets = ()
        for ob in self._uniqueProviders(('sheets',)):
            sheets=sheets+ob._PropertySheetsFor(client)
        return sheets

I'm not sure about the semantics of this though.
With this method added, when a specialist is asked _PropertySheetsFor,
it looks in its own plugins only. It does not look in any of its Racks.

I guess it'll do for now.
