Yes.

Thanks, that did the trick! Now I can start Emacs as below, and I can
log into the remote machine with Tramp 2.5.0.2.

    emacs -Q -L ~/.emacs.d/elpa/tramp-2.5.0.2

However, at the end of the Dired buffer, I still get:

    //DIRED// 69 70 128 130 188 200 258 273 331 345 403 417 475 493 551

    3773 3831 3837

And, I just figured out that I don’t even need to load tramp explicitly.
Now, Tramp 2.5.0.2 from Elpa works also when I start Emacs as usual with
my standard configuration. That’s all after deleting the `.elc` files.

Thanks, but no need for that anymore!

Still, the issue with the Dired buffer remains.
