A nasty bug with the locale prevents even gdm from appearing

[Paulo Levi]

If you install gnome shell (i only fixed the problem later, but i
tried it even on a the default raring live cd daily build, before
downloading ubuntu gnome), doesn't matter if from root using the
ubuntu GNOME live cd daily (the pen/cd worked) or in addition, adding
the gnome3-team ppa, but when you install and set up the local it
causes gdm and the shell to freak out.

The cause is the locale file not having 'UTF-8' suffixes in most
properties. Adding them allowed me to login.
