1. Conda forge gives us `hypothesis: 3.33.0-py36_0` and pytest is loading it as a plugin
2. Pinning the conda version of `hypothesis` to `3.23` corrects the problem.
3. Uninstalling `hypothesis` solves the problem
4. Pip installing `hypothesis` solves the problem

So, I think we can conclude something went wrong with the conda-forge build of hypothesis or pytest.

Since we don't use `hypothesis`, we can disable it in one of a [few](https://docs.pytest.org/en/latest/plugins.html) ways. I'll open a PR with a fix in a few minutes.
