Robustified version. I think we are close to a fix.

(defun ido-kill-buffer-at-head ()
  "Kill the buffer at the head of `ido-matches'.
If cursor is not at the end of the user input, delete to end of input."
  (interactive)
  (if (not (eobp))
      (delete-region (point) (line-end-position))
    (let ((enable-recursive-minibuffers t)
          (buf (ido-name (car ido-matches)))
          (nextbuf (cadr ido-matches)))
      (if (and nextbuf (buffer-live-p nextbuf))
          (setq nextbuf (get-buffer nextbuf))
        (setq nextbuf nil))
      (when buf
        (if (null (kill-buffer buf))
            ;; buffer couldn't be killed.
            (setq ido-rescan t)
          ;; else `kill-buffer' succeeds so re-make the buffer list
          ;; taking into account packages like uniquify may rename
          ;; buffers.
          (and nextbuf (setq ido-default-item (buffer-name nextbuf)))
          (setq ido-text-init ido-text)
          (setq ido-exit 'refresh)
          (exit-minibuffer))))))
