[ESS-bugs] ess-mode 5.2.1; latest ess does not start R in xemacs 21.5.17 (beta)

[Michael Herron]

Hello.

I just installed ess-5.2.1.  When I try to invoke R using xemacs 
21.5.17 (beta), I get the message

Invalid state: bogus value for 'default-process-coding-system', nil

This is with an xemacs beta; whether the problem is ess or xemacs  is 
beyond me.

Here is the current state output:
