Just a hunch, but what is your TMPDIR environment variable set to when
you run htdig? If you don't have write access to that directory, htdig
won't be able to create the temporary file it uses to pass the document
to the parser, and, believe it or not, if that happens it silently leaves
the document without parsing it.
