Thanks - a bit of googling and I understand. Apologies for my ignorance ;)

Of course I'm now back to the drawing board in terms of discovering the root 
of the intermittent 'unknown node type 0' problem. When it starts happening,  
it is reproducible. So I think my best chance is to install a '-g -O0' ruby 
and continue developing my script untill it happens again, then dive in with 
a debugger.
