Looks like "RESPONSE" is "None".

I do not see how this can happen...

Exactly! - this is why I said I'd never seen this before.

It's a 2.6.1 Data.fs that's been dropped into a stock 2.7.0rc2 release and I get this error.

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.

Quite likely, but I have *no* idea where to start with this. All the modules mentioned in the trackback are Zope supplied ones, not third party ones, so I'd assumed it might be the core software.


once again, thanks for the reply Dieter.
