gdm language list and locale setting

["Miloš Komarčević" <kmilos gmail com>]

Does anyone know where the gdm login screen pulls the language list
from (full name), and from which list is the locale set for the
session?

I couldn't figure it out so far, I think it used to be in the gdm
source tarball, but not any more it seems...

Need to file a bug, just want to know the right address.

Thanks,
Miloš
