According to Joakim Wiberg (HMS):

I can see a couple problems here. First of all, unless your K00117.pdf
is exactly 100000 bytes in length, it's being truncated. You'll likely
need to boost your max_doc_size attribute to something larger than your
biggest PDF to avoid truncation.
Secondly, the error message above seems to come from the parse_doc.pl
script. For some reason, your PDF does not have a magic number that the
script recognises, so it's rejecting it. Try running pdftotext on it
directly, to see if pdftotext can handle it. If that works, there's a
discrepancy between what pdftotext and parse_doc.pl recognise as a valid
PDF, and I'd probably need a sample of such a PDF to fix the problem
in parse_doc.pl. If pdftotext can't handle K00117.pdf directly, you're
not going to be able to index it in any case -- not with this external
parser anyway. In this case, you'll need to see what the problem is.
If acroread can handle the PDF, and pdftotext can't, I guess it's Derek
Noonberg's problem. Is the PDF encrypted or encoded in some way or other?
P.S. I'll be away tomorrow, so I probably won't get to look into this
further until Monday.
