This will work:

x = tarfile.gzopen(sys.argv[1], 'r')

The TarFile class works only for uncompressed tar archive files. 
Whenever you want to open or create a gzipped tar, you have to use 
tarfile.gzopen(). I should have mentioned this a little more clearly in 
the docs.

With the next release, there will be a debug message for this case.
BTW, x.list() prints out the contents of an archive as a directory 
listing, so it'll always return None.

Hope this was helpful.
