This particular C-x C-c puts the following prompt into the minibuffer:

    "Active processes exist; kill them and exit anyway? (Yes or no) "

..

The problem is that instead of being in MBF, the focus has moved to NF.,
obstructing the action of typing "yes" or "no".

Martin's directions for this bug are basically:

Start Emacs with $ emacs -Q -l ~/rudalics3.el

where that file contains exactly:


(setq use-dialog-box nil)
(setq default-frame-alist '((minibuffer . nil)))
(shell)
