I do not have a recipe from emacs -Q
However, I debugged the code that leads to the problem a bit, hoping it
will help. This is from the debugger, just before the error:
* call-process("C:/cygwin/bin/bash.exe" nil nil nil "-c"
   #("convert -size 100x100
   \".emacs-bmk-bmenu-image-file-icon.png\" -resize \"100x100>\" -strip
   23 59 (mouse-face highlight)))
* image-dired-create-thumb(#(".emacs.png"
   0 36 (mouse-face highlight))
* image-dired-get-thumbnail-image(#(".emacs.png"
   0 36 (mouse-face highlight)))
In the minibuffer, which is where the current directory is being picked up, I
have this: c:/foo/bar/$HOME/.  My value of env var $HOME is "c:\\".
I am not using vanilla Emacs completion.  At the time the debugger was
entered (because I placed `(debug)' in the code), the completion
candidates are displayed in *Completions*, and they are (correctly)
all of the files in c:/.
I'm using code that, to display the candidates in *Completions*,
checks whether each is an image file, and if so optionally
displays a thumbnail of the image in *Completions*.  It is this code
that calls `image-dired-get-thumbnail':
(when (and (require 'image-dired nil t)
           (string-match-p (image-file-name-regexp) image-file))
  (let ((thumb-img  (append (image-dired-get-thumbnail-image image-file)
                                                             '(:margin 2)))

Debugging shows that (image-dired-thumb-name ".emacs.png") returns
"c:/foo/bar/$HOME/.emacs.png".  Eventually, `image-dired-create-thumb' is
called, and it calls `call-process' as shown above.
