LANG environment variable not set when switching language in SOAS4 /SOAS5 / SOAS6 / Blueberry

[Carlo Falciola]

LANG environment variable seems not set when switching language in SOAS4
 tested with Italian and French locale on an usb stick created with liveusb-creator-3.7.1 for windows.

This imply thats:
- Turtleart do not find correct strings for the palette components (dynamically generated on first activation)
- Activity names in Sugar home view (list and circle) are shown in english.

Same in soas05.iso

Maybe relate to
Ticket #614 (new defect) fail gracefully if LANG isn't set

I guess it's a Sugar bug in the language switcher...

Maybe...
 In the Trisquel Toast it works fine, and in the XO too...

I also tried to make a check on the source code and everiwhere I saw the LANGUAGE env var to be set by sugar the LANG env var seems to be set too, more or less in the same way, at least as my low python skills let me understand...

Suspect that this is also the main reason for jigsaw-puzzle Activity not showing available (italian) transaltion

I made Ia few test with the Blueberry release:
1 - the LANG variable is not set there when switching with the sugar control panel.
2 - Then I tried to set it manually in the
                 /etc/sysconfig/i18n file with LANG=it_IT.UTF-8
 then everything works fine, turleart, activities name, etc....

3 - made the same test with Trisquel and I realized that it uses a diffeent file in a different place:
 /etc/locale.gen in wich appears the LANG setting .

my question is
How can Sugar knows upstream all the possible location&names of file in wich to set the LANG environment variable?
What I'm missing?
Is there a standard command invoked by Sugar to set it in a distro independent way?

tahnks for your help
