Peter> Hi all, Peter> This happened once to me too, but somehow I got around Peter> submitting a bug report. Now, my 0.02 EUR: Peter> You were using shadowfile.el, maybe knowingly or not. Peter> Shadowfile.el has the IMHO bad habit of activating itself Yes, this, right out of shadowfile.el, is a no-no: (if noninteractive (add-hook 'after-init-hook 'shadow-initialize) (shadow-initialize)) I suggest this should just be taken out and the commentary in the file should instruct the user to perform 'shadow-initialize. The unconditional global setting of (setq find-file-visit-truename t) ; makes life easier with symbolic links is a bad thing too. Don't know whether this could be made buffer-local. It should at least be put inside 'shadow-initialize. Your changes are good also I think, if they work well.

Best regards, Adrian Peter> when you just load the library, and this can easily happen Peter> when you browse the Options->Customize menu. Peter> Shadowfile.el creates two buffers, ".shadow" and Peter> ".shadow_todo". If you kill ".shadow_todo" (maybe because Peter> you do not know what it is good for), you'll get stuck in Peter> `save-buffers-kill-emacs', because this tries Peter> `shadow-save-todo-file', which fails if the buffer has been Peter> killed. Peter> The following patch fixes the problem (I hope in the right Peter> way, I have not investigated very deeply). It inserts some Peter> `buffer-live-p' calls to check for killed buffers. Peter> Probably, there are better ways to make shadowfile more Peter> fault-tolerant.
