I changed lines 2704 to 2709 as follows:

              if (isset($file->field_file_image_alt_text) && empty($file->field_file_image_alt_text[$langcode][0]['value'])) {
                $file->field_file_image_alt_text[$langcode][0]['value'] = isset($item['alt']) ? $item['alt'] : '';
              }
              if (isset($file->field_file_image_title_text) && empty($file->field_file_image_title_text[$langcode][0]['value'])) {
                $file->field_file_image_title_text[$langcode][0]['value'] = isset($item['alt']) ? $item['alt'] : '';
              }

Am I crazy?
