nothing has changed in rst except for some message standardization 4  
months ago and build cleanup (makefile) by glynn 6 months ago.
I am wondering whether something in GUI has changed that conflicts  
with what rst is doing (or rst is doing something that the modified  
GUI does not like ) - perhaps there is some computation before  
G_parser is called - would that crash it?
It is 1am now so I need to go but I can look at it tomorrow if I can  
get some hints on what the problem may be.
I never run it from GUI so it might have been there for a while.
