Cant login: openpgp: unsupported feature: public key type: 22

I've created my keys using gpg based on this guide: https://alexcabal.com/creating-the-perfect-gpg-keypair/

But I choose the ed25519 curve as master key algorithm instead of rsa. So I have this keys layout:

```
sec# ed25519/195065AA 2015-12-09 [expires: 2025-12-06]
uid [ultimate] Rodrigo Dlugokenski
uid [ultimate] Rodrigo Dlugokenski
uid [ultimate] Rodrigo Dlugokenski
uid [ultimate] Rodrigo Dlugokenski
ssb rsa4096/067BAD42 2015-12-09 [expires: 2023-12-07]
ssb rsa4096/25290539 2015-12-09 [expires: 2023-12-07]
```

When I try to login from my ArchLinux machine, I got this error:

```
[ERRO keybase main.go:47] 06c openpgp: unsupported feature: public key type: 22
```

Any advice, or this is really a bug/unsupported algorithm? Do I really need to choose RSA as master key algorithm?

```
$ keybase -version
keybase version 1.0.5-6
$ gpg --version
gpg (GnuPG) 2.1.9
```

Start by reproducing login on ArchLinux with the Ed25519 master key and RSA signing subkeys shown in the report, then trace where the "public key type: 22" error is surfaced. Done means determining whether this key layout is supported and, if not, documenting the required key algorithm or reporting the unsupported-key behavior clearly.
