Unfortunately, QUnit.js actually has an object called module with a property exports and thus store.js gets confused on this check:
if (typeof module != 'undefined' && module.exports)
And storejs thinks it's in a node environment, which it is not. This answer on SO seems to be a good way to fix it: http://stackoverflow.com/a/11918368/835696
(#88) - Fix nodejs check
Agreed, a PR has been submitted, but with no valid justification. I'll write one up tonight and post it.
Fixed in #89.
