I'm not sure there really is much dh-python can do here. Note that there
really are no tests in the upstream package. Cloning upstream's hg you find:
% python3.4 -m unittest discover -v
--
Ran 0 tests in 0.000s
OK
and
% python3.5 -m unittest discover -v
patchqueue (unittest.loader._FailedTest) ... ERROR
==
ERROR: patchqueue (unittest.loader._FailedTest)

ImportError: Failed to import test module: patchqueue

So without dh-python getting involved, the bug is reproducible. I'm not sure
it's a bug in Python 3.5 either really, just a new feature which turns out in
this case to be useful for finding the error early. I guess.
