Recent texlive 2008 installed on Linux Slackware 12.0 system.

I have a file that I can process via texexec and which shows up fine
on my Acrobat Reader, kpdf or xpdf. However another person using
(probably) Windows  keeps getting corrupt file errors when he tries
to read it.   And when I try to run the output pdf through pdf2ps it
blows up with this message:
---------------------------------------------------------------------------------
 **** Warning:  An error occurred while reading an XREF table.
  **** The file has been damaged.  This may have been caused
  **** by a problem while converting or transfering the file.
  **** Ghostscript will attempt to recover the data.
