tramp (2.1.14); TRAMP hangs with sudo and su method after querying my password

[Tassilo Horn]

Enter your bug report in this message, including as much detail
as you possibly can about the problem, what you did to cause it
and what the local and remote machines are.

If you can give a simple set of instructions to make this bug
happen reliably, please include those.  Thank you for helping
kill bugs in Tramp.

Another useful thing to do is to put

  (setq tramp-verbose 8)

in the ~/.emacs file and to repeat the bug.  Then, include the
contents of the *tramp/foo* buffer and the *debug tramp/foo*
buffer in your bug report.

--bug report follows this line--

When I try to access a file with `C-x C-f /sudo:address@hidden:/x/y' I'm
queried for my password.  I enter it, and after that TRAMP hangs.  After
waiting 10 or 20 seconds I've quit the try with C-g.

I've set my default shell (zsh) not to use a fancy prompt when TERM is
set to dumb.  In that case it uses '#' or '%' as prompt, depending on
the user.

I tried using the `su' method, but the hang stays.  The contents of the
*tramp/su* and *tramp/sudo* buffers equal.

How can I debug what's going wrong here?

Bye,
Tassilo
