Test failures with Python 3.4 and enabled warnings

[Arfrever]

When warnings are enabled (using e.g. PYTHONWARNINGS="d" environmental variable), then 3 tests fail with Python 3.4.

Thanks, please re-open if this is not sufficient. I don't have Python 3.4 locally for testing. Will release a new version shortly after confirming that the suite passes in travis.
