The problem is that apt_pkg requires a file descriptor, and this is only available for file objects.
GzipFile and other classes written in Python simply emulate the behaviour of a real file for Python applications, but provide no file descriptor for the uncompressed data. You can work around this problem by writing the data into a temporary file, see tempfile.TemporaryFile[1] for more information.
