[ESS] R-2.3.0 crash

[David Reitter]

One crucial difference between running R from a shell within Emacs  
and from R started by ESS may be that the shell is a log-in shell ("/ 
bin/bash -l"), which picks up environment variables set in  
~/.bash_profile and friends, while a process started by Emacs (even  
in a comint buffer) only inherits Emacs' environment (which is the OS  
X environment, NOT bash_profile). (Disclaimer: in Aquamacs it is the  
same environment, but in vanilla Carbon Emacs, it's not.)

Of course, R shouldn't crash if DISPLAY is empty or set to something  
inappropriate.

Robin, maybe you could report the value of DISPLAY just after you've  
started R from within ESS, e.g. via

Sys.getenv("DISPLAY")
