Right now it's currently failing to find python3.3-dbg, so hopefully this'll do
the trick. https://travis-ci.org/lmacken/pyrasite/jobs/20793923

https://fedorahosted.org/design-team/ticket/214

Before this fix, the following exception gets thrown on Python 3.3:

TypeError: Type str doesn't support the buffer API

Thanks to https://gist.github.com/ssokolow/5496286

This will hopefully get 2.5-3.3 working on travis-ci, as nose should be able to
discover everything just fine.

simplejson will write out unicode escape sequences, but won't read
them.
