What version should I use, where from to get it?

I installed version 0.7.1-3 since that's the current version supported in Ubuntu software center and got:

client, path = get_transport_and_path('https://github.com/symfony/symfony.git')
  File "/usr/lib/python2.7/dist-packages/dulwich/client.py", line 381, in get_transport_and_path
    raise ValueError('Unknown git protocol scheme: %s' % parsed.scheme)
ValueError: Unknown git protocol scheme: https

Then I manually installed 0.8.1 and got:

client, path = get_transport_and_path('https://github.com/symfony/symfony.git')
  File "/usr/local/lib/python2.7/dist-packages/dulwich/client.py", line 719, in get_transport_and_path
    parsed.scheme, parsed.netloc, path='/'))
TypeError: urlunparse() takes exactly 1 argument (3 given)

I see some bug recently closed on github https://github.com/jelmer/dulwich/pull/33.

The question is: is this on github same project as here in lauchpad? What version of dulwich should I use in order to be able to work with https repos and where to get it?

Thanks in advance.
