dom/tests/mochitest/bugs/test_bug440572.html is supposed to test access through Xrays to iframes by name, even if they would shadow a WebIDL property. We've switched away from that behaviour, so it should be failing. It doesn't fail because the code that deals with the exception from accessing the property tries to postMessage the exception directly, which throws another exception. The test doesn't count the number of messages it gets, so the missing postMessage's are just ignored.
