I have tried to fix it like this:

diff --git i/conftest.py w/conftest.py
index 2f844fd..ca87ccf 100644
--- i/conftest.py
+++ w/conftest.py
@@ -21,7 +21,7 @@ def run(self):

                     self.path, output.decode('utf-8')), pytrace=False)

     def __repr__(self):

But that then results in an internal error with py.test:

Via #499 (comment).

Submitted for pytest at pytest-dev/pytest#1178.
