Ok. Can you please run test__locale in verbose mode to find out what
the last locale is that it uses? Let's call it X.

Can you please then run interactively

locale.setlocale(locale.LC_NUMERIC, X)
print '%07.2f' % 42

It appears from the test results that this gives '0042,00' for
you; please confirm that it does.

It is bad that test__locale does not restore the locale, but perhaps
we take out that test entirely. However, the behaviour of % is not
supposed to change, so we need to investigate why it changes on your
machine.
