this slightly modified tip from 
http://emacs.wordpress.com/2007/01/22/killing-yanking-and-copying-lines/
seems to work fine

(defadvice yank (after indent-region activate)
   (when (member major-mode '(c++-mode emacs-lisp-mode python-mode c-mode))
     (unless mark-active
       (exchange-point-and-mark))
     (indent-region (region-beginning) (region-end) nil)))
