Comment 2 for bug 434199

When running an installed LottaNZB, it suffices to run locale.textdomain (because the translation files are in a standardized directory). Would you mind checking if the "locale" module has a "textdomain" function on your system by launching a Python shell using "python" and:

import locale
locale.textdomain

This prints "<built-in function textdomain>" on my system.
