This causes _ to become a local that is left undefined on one
branch of the if. You need to ensure it's always defined. Here's
one way that should work:

gttran = _

def foobar(translate):
     def _(txt):
         if translate:
             return gttran(txt)
         else:
             return txt
     return _('Hello')
