That used to happen to me quite often, until I wrote this:

(defadvice toggle-input-method (around confirm-toggle-input-method activate)
  "Prevents user from accidently enabling
    mule-input-method by requiring confirmation"
  (if (or current-input-method
	  (ad-get-arg 0)
	  (y-or-n-p "Turn on mule-input-method [C-\\]? "))
      ad-do-it)
  (message nil))
