Comment 3 for bug 401586

To be clear, this affects production as well.

Perhaps opening a new bug would be appropriate, but I should record the saga of me trying to fix it somewhere.

I made a zope.publisher 3.5.8 and tried to put it in Launchpad. It turns out that 3.5.7 had introduced an incompatible change (! :-( ) that meant that we could not use it, or 3.5.8, without subsequent changes.

I reinstated Jono's changes. Now we need to make a new zope.publisher without the backwards incompatibility and try again.
