After a gdb session, 22 frames deep, it turns out this is a way
of reporting "file not found". Call me old fashioned, but instead of a 
scheme backtrace pointing into 4300 lines long scheme boot 
code (without even telling its full path), I would find a "File not found: 
<full path to the file that is actually missing>" more useful.

The bug is easy to reproduce: take a clean system where gschem is not 
installed, compile everything but don't install, then cd gschem/src and 
run ./gschem (the shell wrapper).
