On my 14.04 *buntu box, requests-cache is 0.4.13. But I used: pip install
--upgrade requests-cache to get it. My newer boxen have 0.4.13 available
as packages (apt-get.)

In:

     /usr/lib/python2.7/dist-packages/requests_cache/core.py

or wherever your packages live, you should see: self._cache_expire_after = expire_after.
And expire_after is an instance of timedelta, not an int.
