@kislinsk: Please don't simply assign me directly tasks. I don't want a over croweded task list where I loose the overview. Additionally it would be a false friend because it suggests that someone (me) is tacking care of it. Regarding my current to do list, this could take a long time if you are waiting for me.
Regarding the topic: I assume it was introduced when T3 added the new reader (so I would ask T3 to fix it). Now the found candidate is the new reader and not the string encoded in the test. Switching to the new reader ID is a valid refactoring and should do the trick.
