System error -491 is a result of a #_debugstr trap when you
don't have a debugger installed.  If you install Macsbug you
should be able to see what string was intended to be printed out
in the debugger.

If you need Macsbug, I'll be happy to mail you a copy (as well as
tell you what commands to perform to collect information about
what's going on).

BTW, I added bug-mcl@cambridge.apple.com as a CC on this message,
so that this would get archived.
