Please write in English if possible, because the Emacs maintainers usually do not have translators to read other languages for them. Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: 1) created second frame 2) killed second frame after some random editing 3) in first frame, on attempt to kill buffer saw: menu-bar-non-minibuffer-window-p: Wrong type argument: frame-live-p, # checked that function, it checks the value of menu-updating-frame and uses it here: 1564:(let ((menu-frame (or menu-updating-frame (selected-frame)))) 1565: (not (window-minibuffer-p (frame-selected-window menu-frame))))) 4) workaround: (setq menu-updating-frame nil) perhaps menu-updating-frame needs to be nil'd on delete-frame near frame.c:1436: > /* Don't allow minibuf_window to remain on a deleted frame. */ > if (EQ (f->minibuffer_window, minibuf_window)) regards, rob If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'. If you would like to further debug the crash, please read the file /usr/local/share/emacs/23.1.50/etc/DEBUG for instructions.
