Jocky-GTK Error trying to get drivers (12.04.1)

[ooleyguy]

I used the command: sean@elric:~$ sudo jockey-gtk
and go the following error text:

(jockey-gtk:31624): Gtk-CRITICAL **: gtk_icon_set_render_icon_pixbuf: assertion `icon_set != NULL' failed

(jockey-gtk:31624): Gtk-CRITICAL **: gtk_icon_set_render_icon_pixbuf: assertion `icon_set != NULL' failed

If jockey-gtk won't let me install drivers, what do I do?

Try gksu or gksudo instead of sudo..
