Locale not supported by C library

[spe05081]

I keep getting these errors in the terminal:

Locale not supported by C library
What's going on???

For example:
.....................................
thomasps@COLIBRI:~$ sudo nautilus
[sudo] password for thomasps:
(nautilus:7364): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.

(nautilus:7364): Gdk-WARNING **: locale not supported by C library
seahorse nautilus module initialized
Initializing nautilus-share extension

** (nautilus:7364): WARNING **: Unable to add monitor: Operation not supported
.....................................
OR (after installing CompizConfig Settings Manager (ccsm)):
.....................................
thomasps@COLIBRI:~$ ccsm

(ccsm:7940): Gtk-WARNING **: Locale not supported by C library.

trying typing in "gksudo nautilus" instead of sudo nautilus and tell what happens

As for Compiz, I can't help there ...i'm still relatively new to ubuntu myself

Same thing:

thomasps@COLIBRI:~$ gksudo nautilus

(gksudo:16765): Gtk-WARNING **: Locale not supported by C library.

Check your timezone and language setting by entering the following in a terminal:

sudo dpkg-reconfigure locales

Can't tell where from but for North America set for en-us

Just tried here is the result:

Looks like there is something missing here. I live in (English) Canada, so my locale should be set to that, if not US. Any clue as to how to fix this?
