Unable to pick select another language for the section in 3.10

[Fran Dieguez]

Hi,

I'm using Ubuntu GNOME with GNOME 3.10 in English language. I've tried 
to change to the Galician language but I cant find it in Region & 
Language -> Language option list.

I've installed language-selector-gnome to test if I could do this with 
it. And I could. From this one I can find Galician listed.

So, I suppose that this is a bug in the g-c-c. Anyone can reproduce this 
too?

I'll try to report it in launchpad.net tomorrow, it someone can confirm it.

Regards
