What I can say is that I can reproduce the problem with a fresh GNU
Emacs 22.0.94 and builtin Tramp 2.0.55 (thanks for the example foo.rej).

With Tramp 2.1.9-pre from its CVS, same Emacs, this problem doesn't happen.

Hard to debug, because everything freezes. I suspect some concurrent
process filters fighting each other. I'll come back later (but this
might last one or two days).
