I don't understand why this library should go out of its way to support the old
behavior when it seems like the only thing it breaks is tests that assume
something that was never guaranteed and where you can get the old behavior in
just two lines

I bumped into a similar issue with mimetypes.guess_extension on Arch Linux
64-bit in February. The behavior is still present in python 3.4.3.
$ python test.py

$ python test.py

$ cat test.py
from mimetypes import guess_extension
print
