[Zope] Zope 2.6.1 and xml.sax.expatparser problems

[Tom Emerson]

Greetings,

I have a (Python) external method that imports a module Foo which in turn
imports a module containing

from xml.dom.minidom import parseString

This results in the following traceback:

Traceback (innermost last):
  Module ZPublisher.Publish, line 98, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object

  Module xml.sax, line 76, in make_parser
  Module xml.sax, line 101, in _create_parser
AttributeError: 'xml.sax.expatreader' module has no attribute 'create_parser'

I can load Foo directly in Python without issue, so this appears to be
somehow related to Zope. It was my understanding that external methods
ran without "interference" from Zope's security mechanism.

This is running on FreeBSD 4.6.2-RELEASE-p2, Python 2.1.3 (with
FreeBSD thread stack patch), and Zope 2.6.1. Both Python and Zope were
built from source.

I'm at a loss to explain this lossage. Anyone have any ideas of what I could try?

TIA,
