The Ethereal README file contains a short explanation of how
to produce a stack trace with the ethereal binary, the core file, and
gdb. Can you do that and send the stack trace to
ethereal-dev@xxxxxxxx. We've had a report of another core dump caused
while processing SMB traces... this might be the same.
