R not running inside emacs any longer

[Faheem Mitha]

Dear People,

I'm running Debian (2.2r3) with 

||/ Name           Version        Description
+++-==============-==============-============================================
ii  ess            5.1.18-0       Emacs statistics mode, supporting R,S  
ii  r-base         1.3.1-1        `GNU S' - A language and environment for
ii  emacs21        21.0-0.1       The GNU Emacs editor.
ii  emacs20        20.7-2         The GNU Emacs editor.
ii  xemacs21       21.1.10-5      Editor and kitchen sink

The ESS and R binaries are by Douglas Bates.

It is extremely puzzling, but R/ESS was working just fine with GNU Emacs
20.7 and after I posted to this list back in late July, GNU Emacs 21
prerelease was working just fine too.

However, when I checked it recently, R would not run any longer on either
of these GNU Emacs versions. When I try to run R I get "selecting deleted
buffer". I recognise this error message from when I have deleted the ess
buffer accidentally, and sure enough there does not seem to be an ess
buffer on startup.

However, R works fine with xemacs and also on the console. Go figure. Does
anyone have any idea what I might have screwed up?

I enclose my .emacs in case it is breaking something. Please CC me; I'm
not subscribed to the list. Thanks in advance.
                                     
                                  Best regards, Faheem Mitha.
