Cannot open file in emacs from google chrome on mac os

hi,

i don't know what i'm doing wrong, but i can't force google chrome to open a file in emacs client.

$EDITOR=/Applications/Emacs.app/Contents/MacOS/bin/emacsclient --create-frame --no-wait

the link in the exception page looks ok:

emacs://open?url=file://filename&line=nnn

still upon clicking there is no frame opened. i guess i should set something up in chrome or zsh or ...?

any ideas?
