I use the gnome desktop environment, and whenever I try to open the gnome control center I get an error saying:

I have tried re installing gnome control center, but it hasn't worked. How do I solve the problem? Thankful for answers.
UPDATE:
this is the message from the command cat /etc/default/locale

. Is this something that just started to fail for you? Do you have any other account on this system that you can log into and try this?
