What is the expected behaviour for FileReader.readAsXXX(null)? Currently I think both IE10 and Chrome fail silently and there are no events fired whereas Firefox appears to throw an internal NS_ERROR_INVALID_POINTER exception. The spec doesn't seem to state this explicitly and I can't tell if there is supposed to be an implicit requirement from WebIDL. Perhaps the expectation is that this falls into the error condition and should set readyState to DONE, result to null, and process the error steps? Any thoughts? Adrian.
