Other Software source properties not properly set

[Forage]

Since Ubuntu 13.10 (complete clean install or upgrade from 13.04), software sources aren't properly added through the GUI. Part of the URI is placed in the distribution section and the value of what should be placed in the distribution section is added to the components section. The result is errors when updating the software sources.

Steps to reproduce:
1) Open "Software & Updates"
2) Go to the "Other Software" tab
3) Add a new source like a PPA. Example: "ppa:gnome3-team/gnome3-staging"
4) Click on "Edit..." for the new created source

Result:
URI: http://ppa.launchpad.net/gnome3-team/gnome3-staging
Distribution: /ubuntu
Components: saucy main

Expected result:
URI: http://ppa.launchpad.net/gnome3-team/gnome3-staging/ubuntu
Distribution: saucy
Components: main

Changing it manually will give you key errors on update afterwards.

Using "sudo add-apt-repository ppa:gnome3-team/gnome3-staging" in a terminal works as expected.

I'm running Ubuntu GNOME 13.10, should that makes any difference.
