#31 ming-0.5.4 (and 0.5.0) tests fail with python2.7, pass with 3.4

[austin987]

I extracted tarball, cd'ed into folder, and ran:
python2.7 setup.py sdist test

which failed:
ERROR: test_mr_replace (ming.tests.test_mim.TestMRCommands)

In total 6 tests fail:

all with the same JSError. Repeating the tests with python3.4 setup.py sdist test worked.
