Fix-nonhinting produces ImportError: cannot import name 'parse' from 'gflanguages'

Hi, I am trying to run fix-nonhinting on a variable font and I am getting the following error:

Traceback (most recent call last):

Any ideas what is causing it?
I am running gftools 0.9.77.dev10+gb025165 and I haven't had issues with previous versions.
