Bisecting has been harder than expected, due to several reasons. At
least I have found the first problematic commit in Emacs, it is
6de77cfa9da18c5e3765c6202b61cef86409e130.

I will still need some time to find a final solution, but for the time
being you could set tramp-use-ssh-controlmaster-options to nil before
you open a remote connection. This shall prevent the problem. I would
appreciate if you could confirm this.

Now I have nailed the problem, I'm quite optmistic to solve it until
release of Tramp 2.5.0.3, scheduled for end of the month.
