"Open in terminal" not working on nautilus as root

When using natilus as root, open in terminal used to work as using with any user. However, when I press open in terminal when using nautilus as root now, it does nothing.

How to solve it?

The error:

GLib-GObject-CRITICAL **: g_object_set_data: assertion 'G_IS_OBJECT (object)' failed

Putting aside any possible damage you've done via sudo nautilus command you could just install & use the nautilus extension nautilus-admin, requires restarting nautilus after install

sudo apt-get install nautilus-admin

It provides

* Open as Administrator: opens a folder in a new Nautilus window running with administrator (root) privileges. * Edit as Administrator: opens a file in a Gedit window running with administrator (root) privileges.

Does so thru a policykit policy.
