Setting process-connection-type to non-nil can make other things fail.
Especially it can cause subprocesses to lose some of their output. I have
experienced this with AUCTeX. So I have in my .emacs file:

(setq process-connection-type nil)

And this causes tramp to fail in the way you described.

I got around this with the following code:

(defadvice tramp-maybe-open-connection 
  (around set-process-connection-type)
  "Set process-connection-type to pty."
  (let ((process-connection-type 'pty))
(ad-activate 'tramp-maybe-open-connection)
