Not surprisingly, though I don't understand why, this is fixed by the patch at https://bugs.webkit.org/show_bug.cgi?id=42578.

However, I don't think the problem here is QNAM related like the other failures resolved by 42578. So it would be good to understand why the patch at 42578 fixes it.

Some debugging reveals that the NodeList is getting inspected in DumpRenderTreeSupportQt but for some reason the QVariantList passed back to the runtime object contains null values by the time it is inspected in the test. The QVariantList is there, it has the right length, but the values in it are 'undefined'.

To me this suggests a problem with the state of the LayoutTestController runtime object after a new document has been loaded in the same QWebPage. This may also be a problem during normal navigation so it could be a real bug.
