hmm why?

It doesn't matter, as callbacks must not throw exceptions without catching
them themselves. If they do, they are already buggy and invoke undefined
behaviour - causing EBADMSG is then the least of the problems.

In fact, if caught via this mechanism it at least has a chance of getting
reported in a defined way (although it's still a bug).
