After trying what you said, more bugs appear. (=���������=')

If I run `sudo emacs`, 

- An error happened.
- A terminal emacs is open.
- The open emacs's process name is `emacs-gtk`.
- There is an additional process `dbus-run-session`.

If I run `EMACS_TOOLKIT=gtk sudo emacs`, 

- An error happened.
- A terminal emacs is open.
- The open emacs's process name is `emacs-gtk`.
- There is an additional process `dbus-run-session`.

If I run `sudo emacs-x11`, 

- No errors happened.
- A terminal emacs is open.
- The open emacs's process name is `emacs-x11`.

If I run `sudo emacs-gtk`, 

- No errors happened.
- A terminal emacs is open.
- The open emacs's process name is `emacs-gtk`.

If I switch to root via `su -`, and then run `emacs`

- An error happened.
- An X emacs is open.
- The open emacs's process name is `emacs-gtk`.
- There is an additional process `dbus-run-session`.

It's difficult to describe all the behavior, why not reproduce that by your
self?
