I am confused because this worked before, and I can "ssh podval" from
the shell (podval is mentioned in ssh/config).

in tramp-sh-handle-file-local-copy:

v ==> [#("scp" 0 3 (tramp-default t)) nil "podval" "/home/sds/.newsrc" nil]
filename ==> #("/scp:podval:/home/sds/.newsrc" 1 4 (tramp-default t))
size ==> nil

Given, that the initial bug has been resolved in Tramp, and that the
other problem won't be reproducible since the remote machine has been
fixed meanwhile, I'm closing the bug. Feel free to reopen if you have
more evidences on the other problem.

Best regards, Michael.
