Status changed to 'Confirmed' because the bug affects multiple users.

[Alberto Salvia Novella (es20490446e)]

It has a severe impact on a large portion of Ubuntu users.

[François Jacques (francois-jacques)]

Not sure if that would quality for showstopper, but it is a major problem indeed. I had to uninstall gnome-settings-daemon and unity-settings-daemon through aptitude then reinstall them before retrieving some normality. I consider myself as expert user and it took me about a half-hour to get through it. I expect most users to give a lot of bad press instead.

Can't install aptitude to uninstall gnome-setting-daemon. Can't install anything.
