------------------------------------------+---------------------------------
 The list of available languages should not be taken from the system
 locales (listed with locale -a), but from the list of translations the
 Sugar core provides (e.g. dpkg -L sugar|grep MESSAGES$).

 Even if the only system locale is C, all languages should work in Sugar if
 the LANG and/or LANGUAGE vars are set properly, something that can be
 managed by gdm. If the user can choose the language this way, the system
 doesn't need to provide all the locales, saving space and compilation time
 -installing all the locales in a slow laptop is a pain in the ass-.

 As an example, the Sugar live cd I'm working on -using Trisquel GNU/Linux
 Edu-, does only include the English locale, but allows you to select other
 languages at boot time. Sugar runs properly in that language, but does not
 list the available Sugar languages if you start the system in other
 language than English -in fact, the language selection dialog fails to
 open-. If you choose English, then you can't select all the languages
 provided by sugar either, just English, Dari, Kreyol and Pashto (maybe a
 parsing error?)

 If someone wants to test the iso I've made, it can be downloaded from
