Error when try to publish post

[jsalinas]

When I try to publish my post with this:

speechhub manage --publish-post hello-world2012-Apr-11.meta.json

I get this messages:

Traceback (most recent call last):

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

Am I missing something?

EDIT: using Ubuntu 11.10 with Python 2.7.2

Same problem here, using Mac OS X 10.7. with python 2.7.1.
