BUG: Error in RetrieveProductRibbons when categoryPageIds array is empty

Hello.
Some of our product ribbons aren't displaying.  After a bit of investigation of narrowed it down to the Ajax request to RetrieveProductRibbons being passed an empty array.  To reproduce, go to this page on your demo site:http://demos.nop-templates.com/apple-icam.  Open Chrome developer tools, click the Network tab and filter the request types by XHR and reload the page. You should see the RetrieveProductRibbons request getting redirected to the custom errors page.

This image shows the error as I see it when testing on localhost: http://imageshack.com/a/img538/5283/xPWZnB.png

I also get this error in the error log:

System.ArgumentNullException: Value cannot be null.
Parameter name: source
   at System.Linq.Enumerable.Distinct[TSource](IEnumerable`1 source)
