[Bug 952181] Re: update-manager crashed with AssertionError in saveDistUpgrade()

[PhoneixS]

It happened to me when I have added a ppa (ppa:otto-kesselgulasch/gimp),
tried to update, and it mentions that gimp can't be installed (I think
is because the package has wrong dependencies), and then I pushed
Configure button ("Configuración...") and deleted the ppa entries in
Software Origin ("Origenes del Software"), click Ok and then in Check
("Comprobar" as I have Spanish version), the windows saying to send the
error report appeared.

Sorry if my English isn't very good.
