No one is expecting the Spanish Inquisition!!! 

Now that we have that all cleared up :o)  I can confirm that this
is a bug in 22.3.1.  Somehow, that setting of ess-bugs-font-lock-keywords
triggers the bug since it does not exist with the default setting.  As I
suspected ESS 5.3.11 is no help here since it is a GNU Emacs problem.
So, I guess you should file a bug report with them if one is not already
there.  I know that there is supposed to be a beta for the next release
of GNU emacs, but I don't know where you can get it.  There is always
XEmacs which does work correctly in this case.
