[sane-devel] pdf from xsane with errors

[E. MARC]

Hello,

I tried to change quality of a PDF document with the following command line
erwan at PC1:~/LotissementChenaie$ gs -q -dSAFER -dNOPAUSE -dBATCH -
sDEVICE=pdfwrite -dPDFSETTINGS=/printer  -sOUTPUTFILE=NewDocName.pdf -f 
DocName.pdf 

My OS is Debian Squeeze.

I got the following result:
====
GPL Ghostscript 8.71: Set UseCIEColor for UseDeviceIndependentColor to work 
properly.
   **** Warning:  File has an invalid xref entry:  4.  Rebuilding xref table.

   **** This file had errors that were repaired or ignored.
   **** The file was produced by: 
   **** >>>> XSane 0.994 <<<<
   **** Please notify the author of the software that produced this
   **** file that it does not conform to Adobe's published PDF
   **** specification.

Where should I place the information? is it sane (It think not), is it specific 
to Xsane or is it for the PDF generator used by Xsane?

Regards
