Strange error, possibly a bug in nose. May need to use the versions in the log file to recreate this oddity.

[jayvdb]

My guess is that moban python files are not declaring an encoding, and hitting some bug in older minor releases of Python.

The complete log (attached) says it is libpython3_6m1_0-3.6.5-lp150.1.5

I tested 3.6.5 in https://travis-ci.org/jayvdb/moban/builds/489894834 , and it is green :/
