Otherwise the build can fail with the following error:

      File "/usr/lib/python2.7/dist-packages/sphinx/environment.py", line 791, in read_doc

        transform.apply(**kwargs)

        if has_child(node.parent, nodes.caption):
      File "/usr/lib/python2.7/dist-packages/sphinx/transforms.py", line 117, in has_child
        return any(isinstance(child, cls) for child in node)
    TypeError: 'NoneType' object is not iterable

The error could be reproduced with lp:autopilot/legacy branch from Launchpad.
