Thanks, fixed this (in repos). The code assumed that there always
was a message.

I've added the stack traceback to the output. It does not become
less confusing, though:

This is LuaTeX, Version snapshot-0.25.3-2008042911 (Web2C 7.5.6)
(error.tex
! LuaTeX error [string "luas[0]"]:1: test error
stack traceback:
         [C]: in function 'error'
         [string "luas[0]"]:1: in main chunk.
l.4 \directlua0{error('test error')}
                                      % B
?
  )



Best wishes,
Taco
