Bug Description

The summary is pretty self explanatory, the plugin contains this bit in the code:

def _get_info(a_branch):
    """Figure out how long the remote ancestry is."""
    starting_revno = a_branch.revno()
    if starting_revno is 0:
        return 0, 0
    last_rev = a_branch.last_revision()
    anc = a_branch.repository.get_ancestry(last_rev)
    assert anc[0] is None
    # anc always includes 'None'
    return starting_revno, len(anc)-1

Obviously since get_ancestry is removed from bzr 2.6 the plugin does not work

Confirmed that it doesn't not work due to this reason in a standard Ubuntu 14.04 (LTS).
Any workaround?

I am attaching a potential patch that worked for me with bzr 2.7.0.
The patch should work for bzr versions where the Repository.get_ancestry() has been deprecated and replaced with graph.iter_ancestry().
