@User I don't have gnome and gnome terminal (i don't have a Desktop environment at all) However the gnome-terminal man page shows there is a -e option and a -x option:

OPTIONS

-e, --command=STRING
    Execute the argument to this option inside the terminal. 
-x, --execute
    Execute the remainder of the command line inside the terminal.

So my suggestion is to try

-e

or

-x

, as done with xterm.
