Message-ID: <871ro2w9wx.fsf@piccolo.i-did-not-set--mail-host-address--so-tickle-me> (raw)
In-Reply-To: 87fvt3sf00.fsf@bye.fritz.box


I allow myself to revive an old thread, as I encounter today the exact
same problem: Emacs crash in org mode at line ending with the following

  Debugger entered--Lisp error: (wrong-type-argument char-or-string-p nil)
  funcall-interactively(org-self-insert-command 1)
  call-interactively(org-self-insert-command nil nil)

I confirm that I've the same variable set in my Emacs config file:

  (setq-default auto-fill-function 'do-auto-fill)

Which I take from the Emacs Wiki AutoFill page¹, with the explanation
of: « If you would like to enable auto fill for all major modes, you can
add this single line to your configuration ».

¹ https://www.emacswiki.org/emacs/AutoFillMode

To fix this, I simply replace the last line of
`org-comment-line-break-function' (in ./lisp/org.el, line 19723) from:

  (insert-before-markers-and-inherit fill-prefix)


  (when fill-prefix
    (insert-before-markers-and-inherit fill-prefix))

But I must admit I don't know all the implications of such a change. In
my case, it does the job perfectly well, but maybe I miss something?

I run make test and every thing goes fine too.

I would like to suggest to fix the method
`org-comment-line-break-function', in order to support user change of
the variable auto-fill-function, as it seems to be a common thing. What
do you think?

Have a good week-end,
