update-manager exits cleanly when trying to upgrade to quantal

[Olivier Tilloy]

Running up-to-date precise, I want to upgrade to quantal.
I run `update-manager -d`, I click on "Upgrade", the release notes are displayed, I click on "Upgrade" again, I am prompted for my password, and after entering it update-manager exits cleanly.

Here is the output I get in a terminal:

osomon@granuja:~$ LANGUAGE=C update-manager -d

I can confirm that I’m now able to start the upgrade to Quantal.
Thanks Michael and Jean-Baptiste for the prompt fix!
