I've got an application that accepts PDF file uploads and stores them in a BLOB column in MySQL. Another application pulls data from the database and sends it to the browser. When the database is queried the BLOB column is written to a file in a public HTML directory and a link is sent to the browser.

My problem is that when users click on the link the Acrobat plug-in loads and then errors out with "Object Label Badly Formatted". If I move the PDF to the directory myself then it loads correctly in the browsers. ls -Fla on the directory shows that the two files (uploaded through the application and copied in with Samba) have sizes that differ by 8 bytes (the uploaded file is larger).

Any ideas of where to look? Here's the code that is accepting the upload:
    my $pdf_name = $cgi_query->param('event_pdf');
    my $pdf = 'EventPDF';
    if ($pdf_name){    #A file (supposedly a PDF) has been sent in the
+ post data.  Load it into $pdf for storage in events table
        binmode($pdf_name);
        while (<$pdf_name>){
            $pdf .= $_;
        }
        $pdf = $db->quote($pdf);
    }
    my $mime_type;
    #(Not very robust) type checking for uploaded file.  This is depen
+dent on the browser behaving
    $mime_type = $cgi_query->uploadInfo($pdf_name)->{'Content-Type'} i
+f $pdf_name;
    if ($mime_type){
        return $self->display_error("Attached file is not a PDF\n") un
+less $mime_type eq 'application/pdf';
    }
