http://www.zope.org/Products/Zope/2.2.0b3/
This release resolves the "len of unsized object" error some folks were seeing with their SQL methods as well as an issue with broken installed products causing a recursion problem instead of appearing as normal "broken" objects.
For more information, see the CHANGES.txt file for the release. If you are still using a 2.1.x version of Zope, be sure to see the document upgrading to Zope 2.2 for information on the recent changes to the Zope security model and other upgrade information.
