Indeed, there’s a bug.  :-/

With your patch, I get:

msmtp uses a GnuTLS that is different from from both other GnuTLS.

I think the bug has to do with the fact that GnuTLS has a replacement
and at the same time needs to be grafted (the libidn and libgcrypt
grafts apply to GnuTLS).

In the meantime, I suggest that you apply the patch anyway.
