Object doesn't support property or method 'headers'

Hello,

We are getting the following error in our project:

TypeError: Object doesn't support property or method 'headers'

Debugging reveals this is indeed the case:

This only seems to happen some of the time, but I cannot seem to reproduce the success case consistently.

Any ideas?

Will need more details. Is this a browser related issue?

This is a WinJS app. I did some digging and this might be caused by using GET on a local resource, which we sometimes do, but I have not had the chance to confirm yet.
