This is a problem in emacs-22 too, with the difference that there
"emacsclient /tmp/test.c" prints an error:
-error Unknown&_command:&_/tmp/test.c

The problem is somewhere in the `set-process-filter' defadvice.  Doing:

emacs -Q -f server-start --eval '(setq follow-intercept-processes nil)' -f follow-mode

makes emacsclient work.

Which is yet another reason not to like defadvice in the emacs sources...
