Buildout fails: AssertionError: Filename ...

Continuing after #20. I commented out ${buildout:python24-parts} (I only really need 2.6).
Now buildout fails here:

I see using bootstrap-1.4.4.py fixes this: #11 (closed).
I think the issue will keep popping up unless it's clearer which bootstrap file should be used.
Would it work to always use 1.4.4?

Tracking this in #23 now.
