Hi Devs,

I am running already existing tests before adding one of my own with tox and the test is failing along with pylint which runs after the tests. Pylint is failing because it expects type Node and getting type Str at the affected location.

I have changed the /pylint/tox.ini file to run only /pylint/pylint/test/test_self.py - 

commands = python -Wi -m unittest discover -s {envsitepackagesdir}/pylint/test/ -p {posargs:*test_self*}.py

Traceback:

After initial debugging, I could see that node.elts is a list of strings  = [ '-rn', '--rcfile=/Users/ahirnish/pylint_patch/pylint/pylintrc', '/Users/ahirnish/pylint_patch/pylint/.tox/pylint/lib/python2.7/site-packages/pylint' ]

But I cant figure out how command line arguments got introduced in the chain. Any help here would be great.

Thanks in advance.
