A bug in my favorite function ZClass::_setBasesHoldOnToyourButts :

when changing the bases of non-persistent ZClasses (pluggable brains) they are set to persistent after the change and no more usable as pluggable brains.

Solution:

    def _setBasesHoldOnToYourButts(self, bases):
        # Eeeek
        copy=self.__class__(self.id, self.title, bases,hasattr(self._zclass_,'_p_deactivate'))
...

instead of
     copy=self.__class__(self.id, self.title, bases)

I used there your trick  from DA.py to check wether the ZClass is persistent.

thanks

phil
