Outside of Gtk-based apps LANG is a fallback for unset values of LC_ALL,
LC_MESSAGES, etc. Since your script isn't going to be doing either GnuCash's or
Gtk's localization init you probably need to set LC_ALL instead of LANG. Note
that if you want translations you'll also need to supply LANGUAGES.
Get the debug symbols for Python for your distro and run Python in the
debugger, then run your script from that.

Something is accessing the C++ locale system and it's throwing an exception,
which is what it does when you try to feed it an invalid locale.
