Hi Fernando, many things in a unix system depends on correct language informations, pytone is no exclusion. I don't think that any application should care about you environment, if you really want no language you should set LC_ALL to C. As you can see in your bugreport even dpkg and perl are generating a bunch of warnings about your language configuration. So I think that its not pytones problem to check that environment. I will tag this bug a wontfix, if you disagree with this decision you are free to the discuss it with me.
Best wishes Alex
