 A possible solution:
 {{{
 if ( $key ) {
         // export gets meta straight from the DB so could have a
 serialized string
         if ( ! $value )
                 $value = maybe_unserialize( $meta['value'] );
         // Occationally, line-endings break unserialize()
         if ( empty( $value ) ) // Try normalizing...
                 $value = maybe_unserialize( str_replace( array("\r\n",
 "\r", "\n"), "\r\n", $meta['value'] ) );
         if ( empty( $value ) ) // Adjust string length if needed
                 $value = maybe_unserialize(
                         preg_replace( // e flag deprecated in PHP 5.5.0 I
 think
                                 '!s:(\d+):"(.*?)";!se',
                                 "'s:'.strlen('$2').':\"$2\";'",
                                 $meta['value']
                         )
                 );

         add_post_meta( $post_id, $key, $value );
         do_action( 'import_post_meta', $post_id, $key, $value );

         // if the post has a featured image, take note of this in case of
 remap
         if ( '_thumbnail_id' == $key )
                 $this->featured_images[$post_id] = (int) $value;
 }
 }}}
