I'm not sure if this is a problem or not (I'm not at my home box where I can run tests), but I noticed that you seem to be sending two Content-type headers for filenames ending in .pdf:

print "Content-type: application/pdf\n" if ($filename =~ /\.pdf$/);
print "Content-type: application/x-pdf\n" if ($filename =~ /\.pdf$/);
