Good catch - fixed (http://code.google.com/p/httrack/source/detail?r=889) in
trunk.

There is another issue, by the way: if you break the mirror, "continue an
interrupted mirror" will fail to update the PDF, because the redirect chain is
not processed correctly. This is due to the horribly written redirect code,
handling cache and live requests totally separately.
