No-op PR to trigger CI

[alexholmes]

My other PR #806 is failing in the Python 3.7 build and I'm unable to reproduce the failure locally, just creating a clean PR to verify that the CI build is good.

hey @alexholmes it seems the error is caused by this

Traceback (most recent call last):

I've created #808 in an attempt to fix the build, i'm not too sure if it's the right way to solve it, so i'll wait for @jsleight to review. sorry for this, will take a look at #806 as soon as the build is green

Thanks so much @ancasarb - your fix seems to have done the trick!

I shipped and merged Anca's branch, so let's close this PR and then you can rebase on master in #806
