So it looks like you are suffering from a `process-send-string' of
Emacs (that's why `tramp-chunksize' has been introduced). Strange, it
has never been reported with Debian systems. The only difference wrt
my configuration seems that you're using the multi-tty branch of Emacs.

Do you see a chance to try it with a mainstream Emacs 21.3.50 (aka
22.1.-999, or whatsoever), with `tramp-chunksize' set to nil? In
parallel I'll test with the multi-tty branch of Emacs next days,
hopefully I can reproduce your problem.

(Another test would be with XEmacs 21.4, because the
`process-send-string' problem doesn't seem to appear there. But that
might be too expansive for you.)

Best regards, Michael.
