I believe locale codes are platform specific, so perhaps this ".932" is not
present on these systems. This was always a risk, but there's no other
good way to test this. Given that it's testing a very obscure error case,
one option would be to remove the test. Another would be to find out a
correct locale code to use on each of the platforms.
