    and eval this function in the *scratch* buffer

       (defun protected-yes-or-no-p ()
	 (condition-case err
	     (yes-or-no-p "Prompt ")
	   (error
	   (lwarn 'got-error :warning "%s" err))))

    and call it. When the prompt is visible type

       C-x 3

I think I figured out what happened.
I suspect that you called it with M-:, right?
That binds debug-on-error to t.

yes-or-no-p starts a recursive editing loop, and when there are no
handlers _inside_ the recursive editing loop and debug-on-error is t,
errors invoke the debugger.  So this error invokes the debugger.

I think that qualifies as a bug.  Perhaps the right fix is that
recursive editin levels should bind debug-on-error to nil.
Does anyone see a problem in that fix?
