I don't understand your setup.
Do you
1) start Emacs as a daemon on host A.
2) you then ssh in to host A and try to do emacsclient -c?

That won't work if you have ssh X forwarding on, which is what you seem to have.

The emacs daemon runs on display :0 (or something similar), and emacsclient 
tries to open your forwarded display, localhost:10, which goes to the host you 
came from.  This can never work.  Please clarify if I misunderstood.
