Ember not loading data in Chrome - DS.RESTAdapter has no method extend - google-chrome

Question

I am calling
Hyena.Store = DS.Store.extend({
revision: 11,
adapter: DS.RESTAdapter.extend()
});
It doesn't work Chrome browser with a heap of errors like Uncaught TypeError: Cannot call method 'extend' of undefined and DS.RESTAdapter has no method extend. Anyone have an idea why? It works fine in Safari and Firefox, but only loads 1 in 10 times in Chrome.
Edit: Adding one of the error outputs as requested:
Uncaught TypeError: Object [object Object] has no method 'setup' ember.js?body=1:29481

The solution was discovered in part thanks to #ahaurw01 - his mentioning that he could only reproduce in Chrome Canary lead me to check my Chrome version, which (for reason unknown) had 'dev' affixed to the version number. I re-downloaded Chrome from the website, removing that from the version, and it fixed the problem.
Still a concern for future releases of Chrome, but at least it's working for now.
