[Therion] debug scrap-names crashes if empty scraps

[Bruce]

I notice that;

 

debug scrap-names

 

causes a metapost (?) error with the attached drawing file.  Therion almost
recovers but reports exit code cp2 and produces no pdf output.

 

Admittedly the file is incomplete, a work in progress.  There is a scrap
with point stations and no walls, and there are two empty scraps.  I think
it is the empty scraps which upset the debug process.

 

However perhaps it would be better if metapost just reported the existence
of the empty scrap and then did not try to label it!

(or maybe something else is going on?)
