Missing test

So, when we were both building experimental filter thingies, to be able to verify exceptions and such, this test got lost.

Someone renamed files and tracked those changes in git, and that caused the file to go away. We should talk about git things so we don't do this again. Maybe we should have something that alerts us when the number of tests goes down, and we can acknowledge it for when we're deleting tests... I'm not sure.

I've re-added the test proper and the configs (which were also lost) and now it's correct again.
