when I save a PDF document with this code:

print  "open the original document \n";
my $pdf1 = CAM::PDF->new($doc1);

print "save it to the new location \n";
$pdf1->output($newdoc1);
[download]

I get no errors. However if I use this code:

print  "open the original document \n";
my $pdf1 = CAM::PDF->new($doc1);

print "save it to the new location \n";
$pdf1->cleanoutput($newdoc1);
[download]

I get this error:

Bad request for object 1121 at position 0 in the file

In case it is helpful, the getPrefs method returns this list

    [1] undef,
    [2] 1,
    [3] 1,
    [4] 1,

Doc1 is a PDF document that opens OK in Adobe reader and professional.
