If I understand the problem right, it's actually a Python problem (!). 
We got bit during tutorial I gave in Germany.

What happens is the following:

package foo
      module foo
          baz = "BAZ"
      module bar
          from foo import baz # fails!

What happens is that Python's import system does relative imports first. 
This means that module bar is not importing package foo as expected, but 
module foo instead.

In future versions of Python there's a way to explicitly force an 
absolute import, which should solve this problem.
