oneconf does not sync: "Invalid Package data from Server"

On my machine (Ubuntu 12.04 with enablement stack) I could trace the error

oneconf.networksync:Invalid package data from server

This comes from:

/usr/lib/python2.7/dist-packages/oneconf/networksync

starting in line 89

    def list_packages(self, machine_uuid):
        """List all packages for that machine"""
        package_list = self._get('packages/%s/' % machine_uuid, scheme=AUTHENTICATED_API_SCHEME)
        if not package_list:
            raise APIError('Package list empty')
        # FIXME: need to do this hack to transform the http request to a json format content
        try:
            package_list = json.loads(package_list[1:-1].replace("'", '"').replace("True", "true").replace("False", 'false'))
        except ValueError, e:
            raise APIError('Package list invalid: %s' % e)
        return package_list

The #FIXME is not enough, because the server delivers a kind of unicode string.
json.loads(package_list[1:-1].replace("u'", "'").replace("'", '"').replace("True", "true").replace("False", 'false')

does it for me

the updated file is added, but its not a proper patch
