This is a problem with the R code that tries to find other versions of
R (e.g. R-1.8.1) and add them to the toolbar.  This is similar to the
problem you had a couple of months ago, let's take this off list...

I got the hint from seeing `ess-r-versions-create' in the debug - it
is trying to create a version of R with no name!
