Upgrade to Zope 2.7.1 breaks old Script (Python)'s history

[ChrisW]

I upgraded a Zope 2.6.2 site to 2.7.1.
Since then, the history tab of all my old Script(Python)'s is broken.

If I try to do a compare between two versions, or just view a historical revision, I get the following error:

2004-06-30T17:41:22 ERROR(200) SiteError http://localhost:8001/myScript/Historica

Script (Python)'s I've created since the upgrade are fine, but any old ones that were around have a buggered history.

this is not critical

There's nothing we can do about old Zope 2.7 bugs anymore.
