 very helpful, thanks.  we can see what is causing the error:

ansi-color-process-output seems to be causing an error.  From a quick
grep of the ess sources:

grep 'ansi-color' *.el brings up nothing so I think you have added
that in your .emacs (or maybe your sysadmin).  Can you see if you have
that in .emacs - and if so, remove it from the relevant hook (
 comint-output-filter-functions ?)
and try a new emacs?
