Hi Eli,

Glad you asked, I now noticed that the problem only occurs when removing
the dot entries via dired-listing-switches (so when the local files
variable is really nil before populating the buffer):

(require 'ls-lisp)
(setq ls-lisp-use-insert-directory-program nil)

;; only occurs if we do not have "." and ".."
(setq dired-listing-switches "-l -h")

;; now create some empty dir, and do
(dired "my-empty-dir")

;; notice that last two lines are not indented, get wrong text
;; properties due to that...

Regards,
Ingo
