Hello,

I often kill org buffers and then Org agenda throws errors at me when i
want to access a line which was that buffer :

Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
  goto-char(nil)
  (let* ((marker (or (org-get-at-bol (quote org-marker)) (org-agenda-error))) (buffer (marker-buffer marker)) (pos (marker-position marker))) (org-pop-to-buffer-same-window buffer) (and delete-other-windows (delete-other-windows)) (widen) (goto-char pos) (org-back-to-heading t) (if (derived-mode-p (quote org-mode)) (progn (org-show-context (quote agenda)) (save-excursion (and (outline-next-heading) (org-flag-heading nil))) (if (outline-invisible-p) (progn (show-entry))) (run-hooks (quote org-agenda-after-show-hook)))))
  (if (and org-return-follows-link (not (org-get-at-bol (quote org-marker))) (org-in-regexp org-bracket-link-regexp)) (org-open-link-from-string (match-string 0)) (let* ((marker (or (org-get-at-bol (quote org-marker)) (org-agenda-error))) (buffer (marker-buffer marker)) (pos (marker-position marker))) (org-pop-to-buffer-same-window buffer) (and delete-other-windows (delete-other-windows)) (widen) (goto-char pos) (org-back-to-heading t) (if (derived-mode-p (quote org-mode)) (progn (org-show-context (quote agenda)) (save-excursion (and (outline-next-heading) (org-flag-heading nil))) (if (outline-invisible-p) (progn (show-entry))) (run-hooks (quote org-agenda-after-show-hook))))))
  org-agenda-switch-to()
  funcall-interactively(org-agenda-switch-to)
  call-interactively(org-agenda-switch-to nil nil)
  command-execute(org-agenda-switch-to)

I'd like to suggest the following trivial patch:
