This seems to be a bug in Acrobat 4. You may want to report it to Adobe.
It works fine with Acrobat 3. The problem seems to be caused by the
-pairs option. If I manually run
acroread -toPostScript -pairs profile_rob_98.pdf /tmp/t.ps
to convert one of my PDFs, Acrobat 4 gives the error
profile_rob_98.pdf: Segmentation Violation Caught.
but with Acrobat 3, it works fine. However, if I try
acroread -toPostScript profile_rob_98.pdf /tmp
it works fine with either version. You may want to revert to Acrobat 3.
Another fix is to write a script to call acroread, stripping the last
filename component from the last argument, and removing the -pairs option,
either in the script or in your pdf_parser attribute in htdig.conf.

PDF titles seem to be a pain in general. Distiller doesn't grab titles
from other applications to put into the PDF. (I don't think it can,
because from the application's point of view, it's just talking to a
printer driver.) All you can do is get into the habit of entering the
title into Distiller's dialog box whenever you create a PDF. On our site,
nobody bothered to do this, so when I adapted the parse_doc.pl script
to work as an external parser for PDFs, I never bothered to do anything
with titles, and instead just put out a title that includes the file name
(just as the script did with other document types).
With acroread, you don't have much choice - you get what it spits out
in the PostScript output. I don't know why you're getting garbage
characters, though. Perhaps they were entered accidentally?
