I clearly should not be allowed to play with sharp objects.  

The following is working now:
--8<---------------cut here---------------start------------->8---
(defadvice org-refile (before org-refile-pseudo-hook dis)
  (setq ido-enable-flex-matching nil))

(ad-enable-advice 'org-refile 'before 'org-refile-pseudo-hook)
(ad-activate 'org-refile)
--8<---------------cut here---------------end--------------->8---
