I can confirm that cherrypicking this commit fixes the problem on my
Arch box which has gnutls 3.6.7 (doesn't occur at all on my Debian box
with gnutls 3.5.8).
Since the only recourse for users hitting is rebuilding --without-gnutls
or (advice-add 'gnutls-available-p :override #'ignore) which falls back
to the obsolete tls.el, I'd say this is important enough to backport to
emacs-26. I'll do that in a couple of days if there are no objections.
