It seems as though an empty value has made its way into your config value for spell-check.localePaths. Can you open your config.cson and see?

If the value of spell-check.localePaths looks strange at all, delete it. It defaults to an empty array (which should not trigger this bug) but should only ever be an array of zero or more strings. I can't imagine how something invalid could've gotten in there (like null or undefined), but as far as I can tell, it's the only way to produce these symptoms.
