    I get the same thing.  I ktrace'd it and it looks like bsdtar
    is trying to examine the gzip header itself... and clearly
    making a mistake.

    If I gunzip | gzip > x.tar.gz  and then tar tvzpf x.tar.gz, that
    works, so basic recognition of gzip files is working properly in
    tar.  It just doesn't recognize THAT particular gzip file.

    So it must be a bug in libarchive somewhere, or perhaps it simply
    does not properly recognize gzip formats?
