I guess this is the point. Emacspeak doesn't respect the rules of error 
handling. Whether it can do its job in a cleaner way - I don't know yet. 
But I'm convinced that there is no bug in Emacs, because the user-error 
is caught and should not see the surface. I also know how to fix 
Emacspeak in the way it was intended to work.

Please close the ticket. Sorry for bothering you.

As an analogy in other languages we can code:
try {
   c = a / b;
}
catch (DivisionByZero) {
   c = -1;
}
That's fine. If someone wants to intercept all the DivisionByZero 
exceptions, which possibly own dedicated error handlers - they do wrong 
thing.

Thanks
