Hello,

For some reasons, sometimes the agenda view works normally, sometimes not.
When not, I have the following error when moving (with arrow down) from line
to line:

#+begin_src emacs-lisp
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  set-buffer(nil)
  (if (markerp m) (set-buffer (marker-buffer m)))
  (save-excursion (if (markerp m) (set-buffer ...)) (save-excursion (goto-char ...) (org-display-outline-path t)))
  (org-with-point-at m (org-display-outline-path t))
  (if (and m org-agenda-show-outline-path) (org-with-point-at m (org-display-outline-path t)))
  (let ((m ...)) (if (and org-agenda-follow-mode m) (org-agenda-show)) (if (and m org-agenda-show-outline-path) (org-with-point-at m ...)))
  org-agenda-do-context-action()
  org-agenda-next-line()
  call-interactively(org-agenda-next-line nil nil)
#+end_src

I don't understand the cause of this, moreover as I have the linked file open
in my Emacs.

Of course, since I've just reinstalled my Emacs, Org, and so on, on a new
Windows setup, I have many small differences with before.

Someone would have an idea for this?

Best regards,
  Seb
