Or more clearly, is the bz2 contains multiple file compressed using -c flag? The -c flag will do a simple concatenation of multiple compressed streams to stdout; it is only decompressible with bzip2 0.9.0 or later[1]. You cannot use bz2.BZ2File to open this, instead use the stream decompressor bz2.BZ2Decompressor. A better approach, is to use a real archiving format (e.g. tar).
