I solved this quite easily (you certainly miss this documentation). This is a snippet of my code that tries to use Picasa API to get all of album from active user:

    http = httplib2.Http(ca_certs=os.environ['REQUESTS_CA_BUNDLE'])
    try:
        http = self.oauth.credentials.authorize(http)
        response, album_list = http.request(Picasa.PHOTOS_URL, 'GET')
        if response['status'] == '403':
            self.oauth.credentials.refresh(http)
            response, album_list = http.request(Picasa.PHOTOS_URL, 'GET')
        album_list = json.load(StringIO(album_list))
    except Exception as ex:
        Logger.debug('Picasa: error %s' % ex)
        return {}

Use the refresh method coming from oauth2client.client.OAuth2Credentials. I think it's even okay to use if response['status'] != '200'. Got to check that!
