[ESS] ESS[R] / Xemacs dies if I hit return before parenthesis matching is completed

Hi Dan, by the look of the backtraces, this could be a problem with
packages other than just ESS.

Can you try the same in a shell?

M-x shell

then type a silly command like
  (pwd)

and hit return before the bounce finishes.

Do you have anything special in your .emacs to do the paren bouncing?

Also, can you try using Emacs rather than XEmacs?
