Sounds like a problem.  Could you send me, via private e-mail, the output of 
uname -a, the approximate script you ran, and a copy of the textdump (gzip'd 
and attached, or via a URL or such)?  The dump file looks quite large, larger 
than I'd really expect, so it could be there's an extraction problem.
