Comment 95 for bug 201786

According to https://bugs.launchpad.net/ubuntu/+source/seahorse/+bug/1420522 it's fixed in seahorse 3.30, which is present in ubuntu cosmic and later.

From https://bugzilla.redhat.com/show_bug.cgi?id=1435924, this should reproduce the problem:
1. Generate a ssh key using the keytype ed25519 and enter a password when creating the key:
$ ssh-keygen -t ed25519
2. Log out from your computer and log in again
3. Start a ssh session to a remote host:
$ ssh <email address hidden>

I tried that with bionic, which has seahorse 3.20.0

Comment #88 hints that trusty is affected and also broke, can someone confirm that please? trusty has seahorse 3.10.2-0ubuntu1

Releases older than trusty are EOL by now.
