There is another option: exception can contain non localized string and 
a thin wrapper will translate them on API layer right before output.
Something like:
print _(str(exception)).

It seems a cleaner solution to me since we don't need to add 
translations all over the code and we call a gettext just once when it's 
actually needed.
