I think there is something wrong in this sql file, causing the error and copy.
but I have not found a solution to overcome 

---* {$to_prefix}attachments
---{
$no_add = true;
$file_hash = getAttachmentFilename(basename($row['folder']), $id_attach, null, true);
$physical_filename = $id_attach . '_' . $file_hash;

if (strlen($physical_filename) > 255)
   return;
if (copy($row['folder'], $attachmentUploadDir . '/' . $physical_filename))
{
   @touch($attachmentUploadDir . '/' . $physical_filename, filemtime($row['folder']));
   $rows[] = array(
      'id_attach' => $id_attach,
      'size' => filesize($attachmentUploadDir . '/' . $physical_filename),
      'filename' => basename($row['folder']),
      'file_hash' => $file_hash,
      'id_msg' => $row['id_msg'],
      'downloads' => 0,
   );

   $id_attach++;
}
---}
SELECT mesid AS id_msg, folder
FROM {$from_prefix}kunena_attachments;
