SOLVED: Gentoo: Incorrect padding, Socket exception, Bad file descriptor

[I realize Gentoo is not a supported xpra platform. I am filing this simply in case it can be of help to others. I will immediately close after filing.]

Symptom:

$ xpra attach ssh://me@somewhere/1

2024-09-09 07:41:32,949 Socket exception: Bad file descriptor (9)

Cause: something called paramiko. Someone with more time than I can maybe chase this down further.

Solution: use --ssh=ssh

$ xpra --ssh=ssh attach ssh://me@somewhere/1
       ^^^^^^^^^
yay happy world
