OK. I propose to stop the search at this point. To be sure that it isn't a regression I will do a regression test next weekend.
It's not a regression, the behavior has always be the same. I just added the error message recently to make it easier to diagnose, so you won't get the error on older versions, but your prefix will still be broken.
