[Zope-dev] Zope 2.12 and Five - setting of Products.meta_types

[Martin Aspeli]

Hi,

Something has changed in Zope 2.12 that is causing tests that use 
PlacelessSetup's tearDown() with Five to fail:

Error in test 
/Users/optilude/Development/Plone/Code/Build/plone/4.0/src/plone.autoform/plone/autoform/tests/../autoform.txt

Sure enough, Products.meta_types is not set. In the Zope2 egg, 
Products/__init__.py contains only the setuptools boilerplate for 
namespace packages. I'm not sure how or where Products.meta_type is set 
these days.

Does anyone know how to correctly fix this? We could make the tear-down 
code in Five more robust, obviously, but I fear that's just hiding a 
deeper problem?
