Fixed by doing:

rm testing/marionette/client/marionette/marionette.pyc

Changing the title to make it easier to find for other people with this problem. Dupe other bugs to this one.

I usually set the PYTHONDONTWRITEBYTECODE output variable to avoid having .pyc files litter my working directories.

Yeah, that's a good solution.. just be aware that it comes with a minor perf hit.

It's also possible to purge all .pyc files in your repo by running:
$ hg purge --all -I "**/*.py[co]"
