TypeError when use doc tools to generate configuration difference

[Chason Chan]

When I use openstack-doc-tools to generate "New, updated, and deprecated options" for Networking service, I failed with "TypeError: 'module' object is not iterable".

More output see the following:

Working on neutron (stable/newton)
Guru meditation now registers SIGUSR1 and SIGUSR2 by default for backward compatibility. SIGUSR1 will no longer be registered in a future release, so please use SIGUSR2 to generate reports.

BTW, I run the following command to generate:

./diff_branches.py stable/newton stable/ocata neutron

Not sure what I am missing. Could you or someone else please help me?
