It's indeed version 0.4.0 I got.
I pinned it to 0.3.5 in versions.cfg and it works now. Perhaps this should
be done in the official versions.cfg, or can't you do that because it's not
needed for everyone? I'm not up to speed with buildout and pinned versions
and stuff like that (yet).

I tried on a testproject to use the 0.4.0 of sourcefactory, but went from
one error to another...
I changed zope.app.form to version 3.7.0 as you suggested, and that indeed
requires zop.schema>=3.5a1
So I also changed that, but while starting up the server, I got this
warning:

Trying the add page dumped this error:

So I figured perhaps the warning is a good hint, and I changed the
zope.configuration to the latest version , being 3.4.1, but that did not
remove the warning, or solve the error.

As the penultimate egg that was used in the error log was zop.app.component,
I tried getting a later version for that one (3.5.0), although it didn't
state anything in the changes log about this.
But while starting up the server, I got this error:
  File
"C:\Docume~1\jm\.buildout\eggs\zope.app.container-3.5.6-py2.4-win32.egg\zope\app\container\browser\metaconfigure.py",

    ImportError: No module named back35

And then I gave up...

I made a bugreport for it: https://bugs.launchpad.net/bugs/319546
