Bit debugging with python and my locale, shows that my locale / python is broken, not the script (that might do some counter measures / pre-check ?):

XXX@XXX-office-antec ~
 % cat silly.py
import locale

print "Hello there"
print locale.getdefaultlocale()

locale.setlocale(locale.LC_ALL, "")
print locale.getdefaultlocale()

This was fixed shortly after it this bug was reported.

ubuntu-release-upgrader (1:0.192.8) raring; urgency=low
