Argh, yes.  This is unfortunately only fixed for 2.6:

http://www.python.org/dev/peps/pep-0366/

We might just add that boilerplate

if __name__ == "__main__" and __package__ is None:
    __package__ = "expected.package.name"

protected by a version check, so your approach continues to work.

I've started using absolute imports because they will become default
eventually, and they do provide some other benefits (see pep if
curious).  For the most part they are innocuous, but this little
glitch will need addressing, thanks.  Now tracked:

Mmmh, if you can track the problem, let me know. Otherwise I'll try to
get to a Windows VM as soon as possible, but it may take me a couple
of days.

Question: had you installed ipython, or where you running from a  source tree?

Cheers,
