remote tramp hangs

Hi,

I am having problems making tramp work.  In a nutshell, "/remotehost:"
works, but "/address@hidden:" doesn't work, though I can passwordlessly
ssh/scp address@hidden  It hangs with the message "Tramp: Found remote
shell prompt on `remotehost'".

Data that may or may not help: miaou=localhost is ubuntu 9.10,
harry=remotehost is openbsd 4.5.  emacs is compiled from
http://bzr.savannah.gnu.org/r/emacs/trunk, revno 98852.  M-x version
says "GNU Emacs 23.1.50.1 (x86_64-unknown-linux-gnu) of 2009-11-30 on
miaou", M-x tramp-version says "2.1.18-pre".  I get the same results
with emacs23* / emacs-snapshot* ubuntu packages and/or tramp cvs,
though.  I also tried a bunch of different tramp methods (ssh, sshx,
scpc, ...) and always get the same behaviour.

What I am doing:

address@hidden:~$ emacs -Q
M-: (require 'tramp) RET
M-: (setq debug-on-quit t tramp-verbose 10) RET
C-x C-f /address@hidden: RET

then I wait for some time, and when it appears hung interrupt with C-g.
