Please describe the problem:
It seems that the command-line options for gnome-terminal are missing the necessary options to launch gnome-terminal with a specified profile, as opposed to opening and *additional* window, which the --window-with-profile option does.


Steps to reproduce:
I have added a launcher to my gnome-panel which runs

gnome-terminal --window-with-profile=ipython

with ipython being a named profile in my gnome-terminal configuration. 

Actual results:
This launcher opens *two* windows -- one with my default profile and another with my ipython profile.

Expected results:
A single window with the 'ipython' profile

Does this happen every time?
Yes

Other information:
gnome-terminal --help explains that this is the intended behaviour, but I think that the intended behaviour is wrong in the case where there are not yet any open gnome-terminal windows.
