It looks like buffer-file-name-localized in gud-format-command is nil
for you, though I don't see how that's possible and I can't reproduce
this here.

(defun gud-format-command (str arg)
  (let ((insource (not (eq (current-buffer) gud-comint-buffer)))
        (frame (or gud-last-frame gud-last-last-frame))
        (buffer-file-name-localized
         (and (buffer-file-name)
              (or (file-remote-p (buffer-file-name) 'localname)
                  (buffer-file-name))))
    ...
         ((eq key ?d)
          (setq subst (file-name-directory (if insource
                                               buffer-file-name-localized
                                             (car frame))))
