I had a look into this.  Unfortunately I only have OpenSUSE Tumbleweed
available.  It doesn't fail for me in Tumbleweed.  (It also doesn't
fail in the CI pipeline for Tumbleweed.)

So I guess this problem is somehow specific to nbdkit or gnutls in
OpenSUSE 15.3.

We can probably ignore this failure, under the assumption it is fixed
upstream.
