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.

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.
