You've tracked the error down to some code that Rich and I added
recently (in the last months);  is there any chance that you could
generate a *Backtrace* buffer that might give us more clues as to what
is generating this erorr?

----
   If Emacs reports an error, backtraces can help us debug the problem.
Type "M-x set-variable RET debug-on-error RET t RET".  Then run the
command that causes the error and you should see a *Backtrace* buffer
containing debug information; send us that buffer.
----

In the meantime, commenting out the code would not be a big loss --
this section of code adds some extra menu items that allows,
e.g. R-1.8.1 to be called rather than just R.
