tar(1) fails to extract a valid archive
$ tar -zxf kwalletcli-1.00.tar.gz
tar: Unrecognized archive format
tar: Error exit delayed from previous errors.
Using g(un)zip(1) and tar(1) works:
$ gzip -cd kwalletcli-1.00.tar.gz | tar -xf -

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?

bsdtar 2.7.1/libarchive 2.7.1 works for me on linux. We have 2.7.0 on DragonFly.

Good catch, bsdtar 2.7.1 changelog contains this line as well amongst
others: "Handle gzip files signed with OpenBSD "gzsig" program." That's
