If any of the subdirs (or even the top dir) is hidden in a dired buffer, `wdired-change-to-wdired-mode' fails. I believe this is happening at `dired--unhide' called from `dired-remember-marks'.
Running 'C-x C-q' , with a hidden subdir results in a "Buffer is read-only" message. 'C-x C-q' works properly after manually unhiding the subdirs.
Recipe is attached, since my mail client seems to strip out control characters.
