fix split on NoneType bug

[Tmacshamgod]

AttributeError: 'NoneType' object has no attribute 'split'
locale -a, for the items that don't have a '_', show the error message abrove

I think the added condition should be
if locale.getlocale()[0] is not None
instead of:
if locale.getlocale() is not None
