Actually, this sounds rather like a problem that happens in Python 2.4 as well.

If you have a package 'foo' containing modules 'bar' and 'baz', and 
foo/__init__.py imports both bar and baz, then 'import foo.bar' will fail 
inside of baz.  You have to use 'from foo import bar' or it doesn't 
work.  We run into this a lot in Chandler, which tries to expose package 
APIs from the package __init__ modules.
