dired-re-dir dont expect human readable format in the file system block size.
If we set dired-actual-switches -lsh, with gnu ls, diredp-next-dirline 
fails whenever the block size contains size units.

emacs -Q:

(let ((default "  15204787   4 drwxr-xr-x  2 user group   4096 Dec  28 17:53 .emacs.d")
       (human "  15204787 4.0K drwxr-xr-x  2 user group 4.0K Dec  28 17:53 .emacs.d"))
   (require 'dired)
   (if (string-match dired-re-dir default)
       (insert (format "default match dired-re-dir\n"))
     (insert (format "default DOESN'T match dired-re-dir\n")))
   (if (string-match dired-re-dir human)
     (insert (format "human match dired-re-dir\n"))
     (insert (format "human DOESN'T match dired-re-dir\n"))))
default match dired-re-dir
human DOESN'T match dired-re-dir

We may fix this modifying dired-re-inode-size to recognize human readable sizes.
