self-insert-command advice is not called when command is run

[M Jared Finder]

If self-insert-command has any advice, that advice is not run when 
self-insert-command is called by pressing a key.  I need this feature for 
balanced-mode, which advices self-insert-command to always insert balanced 
sexps.  (You can see balanced-mode at <http://hpalace.com/tmp/balanced+.el>.

Sample code to reproduce this:

(defadvice self-insert-command (around bug-report)
  (message "Advice called!")
  ad-do-it)
(ad-activate 'self-insert-command)
;; then hit any normal key.
