Unfortunately, now Dired fails to visit a directory:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  file-name-absolute-p(nil)
  dired-goto-file(nil)
  dired-restore-positions(((#<buffer /tmp/> nil 3) nil ((#<marker at 1 in /tmp/> nil 3))))
  dired-revert(nil nil)
  revert-buffer()
  dired-internal-noselect("/tmp/" nil)
  dired-noselect("/tmp/" nil)
  dired("/tmp/")
  dired-jump(nil nil)
  funcall-interactively(dired-jump nil nil)
  call-interactively(dired-jump nil nil)
  command-execute(dired-jump)

Maybe this happens when a reverted directory window is restored
from a window configuration, so point-marker is at 1,
and (dired-get-filename nil t) returns nil in `dired-save-positions'.
