extra-vars parse error with ansible 1.9.1

[subsetpark]

When called from the CLI like this:
battle -K --config-file=config.yml --extra-vars dir_var=/Users/myhome/path/to/dir

I get this error:

Traceback (most recent call last):
  File "/usr/local/bin/battle", line 7, in <module>
    sys.exit(main(sys.argv[1:]))
  File "/Library/Python/2.7/site-packages/battleschool/main.py", line 141, in main
    extra_vars = utils.parse_kv(options.extra_vars)
  File "/Library/Python/2.7/site-packages/ansible/utils/__init__.py", line 787, in parse_kv
    vargs = split_args(args)
  File "/Library/Python/2.7/site-packages/ansible/module_utils/splitter.py", line 73, in split_args
    args = args.strip()
AttributeError: 'list' object has no attribute 'strip'

Looks like battleschool is expecting a string, when actually it gets vars like this: ['dir_var=/Users/myhome/path/to/dir']

@subsetpark what happens if you quote it? All the examples from the docs show quotes. Though I know things have changed over time in ansible. Some tests would be good.

Same issue, single or double quotes.
