Archive reconstruction fails on files with block.compression_method == COMPR_STORING

Reconstruction fails here:

            # we've done files before
            if len(archived_files) >= 1:
                print("Testing with previous file")
                # try compressing with the previous rar file before it
                prev = get_previous_block()
                if prev:
                    prev_file = archived_files[prev.file_name]

archived_files does not contains entries which are written to rar archive directly without compression.

The problem seems to start here:

                        if block.compression_method != COMPR_STORING:
                            _fire(MsgCode.MSG,
                                message="Trying to rebuild compressed file %s."
                                % block.file_name)
                            srcfs = get_rar_data_object(block, blocks, src,
                                        in_folder, hints, auto_locate_renamed)
                        else: # uncompressed file
                            srcfs = open(src, "rb")
