Ah, finding it through google groups shows that the post got truncated
where the backtrace included a null character.  My newsreader shows it
in full, so I guess my news server has a full copy; the ^@ may have
messed up article propagation or something.  I did try to sanitize the
backtrace -- what's the correct way to gather & post a backtrace safely?

Either way, here is the output:
