error in dired sorting on OS XOn OS X 10.5 Emacs 23.2, in dired-mode, if I try to sort by dired-sort-toggle-or-edit with prefix argument --sort=extension or -X, I get: insert-directory: Listing directory failed but `access-file' worked and the dired buffer becomes empty. I tried setting (setq dired-use-ls-dired nil) but this had no effect. dired-sort-toggle-or-edit and sorting by extension seems to work okay on my Ubuntu box.
