Re: [Zope-dev] Zope2.7.0rc2 AttributeError: 'NoneType' object has no attribute 'setHeader'

It's a 2.6.1 Data.fs that's been dropped into a stock 2.7.0rc2 release and I get this error. Whether or not RESPONSE is None should not be dependent on the Data.fs (RESPONSE is recreated for each request and is independent of persistent objects). I have no idea why this is happening, so I was hoping that it was an artifact of the 2.7.0rc2 release itself. Probably, I would start debugging.
