Looks as if I have pretty much the same setting and I run into that
error too, regularly.

If you look closely at the ESS buffer after starting ESS, you will see
after the start up message the following (at least I see this):

R> .help.ESS <- help
R> options(STERM='iESS', editor='emacsclient')

The first line is where, and how, .help.ESS is defined and it resides
in your working space.  Some commands, e.g. rm(list=ls(all=TRUE)) will
delete .help.ESS, and it is after running such commands when I
experience the problem.  A simple

R> .help.ESS <- help

fixes the problem.
