Test errors noted at #153 and #154

If I understand correctly, this will consistently fail until #153 and #154 are fixed. Maybe we should delay introducing it?

[jayvdb]

Consistently failing is fine. At least people can see and start working on the problems.

The Python 2 problems are obviously highest priority, so I expect that will be solved quickly.

The SyntaxError's on Python 3 are easy to fix - then we can assess whether Python 3 support is feasible in the short term -- if not, the Python 3 job can be made 'non-voting'.

I'm checking if we can actually use Travis on this repository. May take a day or two.

[jayvdb]

ok, thanks Adam.

[ricea]

Maybe okay now? Going to try it and see if it works.

[ricea]

Yes, that seems to work.
