Package: paperkey
Version: 1.3-2+b1
Severity: normal
Problem: paperkey causes "Segmentation fault" with ed25519 subkey.
$ gpg --export-secret-key 1DD8D791 |paperkey >paper-secret-1DD8D791.txt
Unable to parse algorithm 22
Segmentation fault
(paperkey works fine with my old rsa1024 key w/o ed25519 subkey)
How to reproduce:
* Add a ed25519 subkey with "gpg --expert".
* Execute paperkey as above (1DD8D791 is my key)

$ gpg --list-keys 1DD8D791

Background:
At Debconf17 gNiibe-san tempted me to use "Modern GPG" and ... I now
have a subkey using algorithm 22 (ed25519) and Gnuk. That's why I have
card-no in the above example and ed25519.
