I just tried your example from above, and I can not reproduce this
error.  Maybe as Suvayu suggested you should try grabbing the latest
version of Org-mode and see if that fixes this issue.

Hi, I agree with your intuition here, but I changed the default inline
header argument so that others would be able to use inline code blocks
and have the results inserted.  To regain the behavior you describe,
simply adjust the value of `org-babel-default-inline-header-args' as
follows in your .emacs file.

#+begin_src emacs-lisp
  (setf org-babel-default-inline-header-args
        '((:session . "none")
          (:results . "silent")
          (:exports . "results")))
#+end_src
