Can't use coverage in Python 3.2

Python 3.2 tests fails since today:

$ coverage run setup.py test

Here's an old job which succeed and failed after retry: https://travis-ci.org/ZuluPro/django-dbbackup/jobs/80029389

When a build starts failing without your code changing, it is often the underlying dependencies that changed and caused the sudden failure. Please compare the old and the new dependency versions to troubleshoot. Thanks.

Looks like there is a major release of coverage, version 4.0.

Ok thanks, my fast fix:

pip install 'coverage<4'

@ZuluPro Thank's for the fix, the issue was driving me mad, and the error is very unhelpful. What is weird is that the issue only happens with Python 3.2 (I'm testing 2 different libraries against Python from 2.6 to 3.2 and even Pypy and Pypy3, no issue at all with all the others).

For those interested I was able to setup codecov (in practice a wrapper for coverage) under all Python versions, look here.
