This is basically wrong. You ignore an error case instead of making it a non-error. Just running the test suite would have shown you how wrong it was ;-)

Anyways, I gave it some thoughts and it is really not fair to ask you to do this. It is actually a pretty delicate change that needs to be done, and it could be done in two different places. I have to think about where it would be best implemented ... In other words I'll do it.
