Indeed, with an M-x R-mode beforehand, the error goes away.
In Aquamacs, R is loaded via site-lisp as below. Instead of running  
"load" from site-lisp, I autoload it. Can't see anything wrong with  
that (I'm sure you'll tell me).

I don't really understand `ess-find-exec-completions', with its i, j  
and k, but my take is that  ess-tmp-dir is "" when it should probably  
be something, and that leads to the current working directory being  
assumed, which will probably fail with the reasonable error we're  
seeing when using tramp mode.  I guess the lesson is that you can't  
count on the working directory being accessible at all times.
Why would `ess-find-exec-completions' want to try a completion with  
the working directory anyways? Shouldn't it just look in everything  
in `exec-path' ?
