duplicity crashes when trying to connect to MEGA

[Imri Paloja]

I'm trying to backup to MEGA(https:://mega.co.nz/), which duplicity supports. I tried this on Ubuntu 15.04, which I am reporting this error from, but also on 14.04. On both version i had installed mega.py via pip.

What happened on 15.04: I executed the following code:

duplicity /home/USERNAME/MEGAsync/ mega://USERNAME:<email address hidden>/MEGAsync

After a couple of seconds, it displayed the following error:
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1500, in <module>
    with_tempdir(main)
  File "/usr/bin/duplicity", line 1494, in with_tempdir
    fn()

    action = commandline.ProcessCommandLine(sys.argv[1:])

    backup, local_pathname = set_backend(args[0], args[1])

    globals.backend = backend.get_backend(bend)
  File "/usr/lib/python2.7/dist-packages/duplicity/backend.py", line 221, in get_backend
    obj = get_backend_object(url_string)
  File "/usr/lib/python2.7/dist-packages/duplicity/backend.py", line 207, in get_backend_object
    return factory(pu)
  File "/usr/lib/python2.7/dist-packages/duplicity/backends/megabackend.py", line 44, in __init__
    self.__authorize(parsed_url.username, self.get_password())
  File "/usr/lib/python2.7/dist-packages/duplicity/backends/megabackend.py", line 104, in __authorize
    self.client.login(email, password)
  File "/usr/local/lib/python2.7/dist-packages/mega/mega.py", line 31, in login
    self._login_user(email, password)
  File "/usr/local/lib/python2.7/dist-packages/mega/mega.py", line 42, in _login_user
    raise RequestError(resp)
RequestError: -9

On Ubuntu Trusty Thar 14.04, after running :

duplicity /home/USERNAME/MEGAsync/ mega://USERNAME:<email address hidden>/MEGAsync

I get the following error:

     BackendException: Error while authenticating client: -9.

For further information, I also asked this on askubuntu.com:

I am hoping to get this working on 14.04
