Bug#403928: Language selection problem

[Alexander Vlasov]

Package: gnome-session
Version: 2.14.3-3

Today I faced strange problem with (I suppose) gnome-session:
After generating new locales and choosing language via gdm menu for
current session, gnome starts, but I receiving a borderless (ie it
happens before starting window manager) window with a message: "Language
<language-here> does not exist; using System default" and everything
reverting to default language.

Locale itself works perfectly, i.e. I'm able to run 
`LANG=<language-here> date' and I receive correct output.

I tried zh_CN, zh_CN.UTF-8, en_US, en_US.UTF-8 -- the same result.
But ru_UA.UTF-8 works fine for me.
