It works fine for me on all versions of emacs including the snapshot
24.1.50.2.   

I can infer from the backtrack where the bug lies. It's these lines  in ess-help

    (if (and res return-match searching)
	(list (match-beginning 0) (match-end 0))

res here can be t if the buffer length is less than 80 chars. Then
match-beginning and match-end are meaningless. 

In any case the buffer should not be < 80 chars. Something else is
fishy over there. 

I will commit a patch, but we would better simplify the help system, as
it's unnecessary complicated.

Vitalie.
