Unfortunately, the additional traces are not visible:

Locally, I see traces like this:

10:10:28.329956 tramp-sh-handle-file-local-copy (3) # Decoding local file 
`/tmp/tramp.21069tQL.log' with `(lambda (beg end) (base64-decode-region beg 
end) (let ((coding-system-for-write (quote binary)) (coding-system-for-read 
(quote binary)) (default-directory (tramp-compat-temporary-file-directory))) 
(apply (quote tramp-call-process-region) [ssh nil ford /tmp/.eagent.log nil] 
(point-min) (point-max) (car (split-string gzip -d)) t t nil (cdr (split-string 
gzip -d)))))'...

Have you pulled Emacs from the repository, recompiled, and restarted Emacs?
