Summary: Gtk::RcStyle#set_bg crashes, Gtk::TextView#modify_bg fails

Initial Comment:
I've been trying to set the foreground/background color
for a TextView widget both via the
Gtk::Widget.modify_bg and the Gtk::RcStyle.set_bg and
neither is working. The modify_bg fails to do anything,
so maybe its not what I should be using (tho
technicially Treeview is a child of Widget, right) but
the RcStyle.set_bg crashes telling me it needs 4
parameters, when the API reference only mentions 2.

Here's a little test program to give you an idea of the
problem:

require 'gtk2'

window = Gtk::Window.new
textview = Gtk::TextView.new
window.add(textview)

window.default_width=100
window.default_height=100

black = Gdk::Color.new(0, 0, 0)
white = Gdk::Color.new(65535, 65535, 65535)

#try setting the colors via the Gtk::Widget functions;
Nothing seems to happen
textview.modify_bg(Gtk::STATE_NORMAL, black)
textview.modify_fg(Gtk::STATE_NORMAL, white)

#what the hell, lets try some other states just because
we can, again nothing happens
textview.modify_bg(Gtk::STATE_PRELIGHT, black)
textview.modify_fg(Gtk::STATE_PRELIGHT, white)
textview.modify_bg(Gtk::STATE_ACTIVE, black)
textview.modify_fg(Gtk::STATE_ACTIVE, white)

#Get the Gtk::RcStyle and try to set the colors via that
style = textview.modifier_style
#this next line crashes saying the function takes 4
arguments, when according to
#
http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3ARcStyle#set_bg
#and
http://www.gtkmm.org/gtkmm2/docs/reference/html/classGtk_1_1RcStyle.html
#it only takes 2
style.set_bg(Gtk::STATE_NORMAL, black)

Gtk.init
window.show_all
Gtk.main

At the very least, either the API documentation needs
to be fixed, or the bug making that function think it
needs 4 parameters needs to be fixed.

I'm using Ruby/GTK 0.12.0
