I'm writing an application for the Ubuntu app showdown and I try to read/write the user's profile picture using this

>>> from gi.repository import AccountsService, GLib
>>> current_user = GLib.get_user_name()
>>> user = AccountsService.UserManager.get_default().get_user(current_user)
>>> print user.get_icon_file()
None
>>> print user.get_user_name()
None

But apparently does not work. Is there another way to use AccountsService with Python? I could not find more documentation about AccountsService and Python.

PS: to test this example you need to install gir1.2-accountsservice-1.0 on Ubuntu 12.04.

$ sudo apt-get install gir1.2-accountsservice-1.0
