Help wanted with GTK+ program

I'm working on a simple GTK+ wrapper around the flash Pandora Radio
player (Pandora.com).

It's very basic right now but I've got it almost working.
I'm using gtkmozembed to fetch and use the player and dbus to detect
multimedia keys.
The only problem I'm having is that the mozembed widget doesn't seem
to recognize the fake keypress event sent to it.

CODE

#!/usr/bin/env python

import gtk
import gtkmozembed
import dbus
from dbus.mainloop.glib import DBusGMainLoop

class Wrapper:
    def __init__(self):
        # Set-up the wrapper for the player

        self.win = gtk.Window() # Create a new GTK window called 'win'

        self.win.set_title("Pandora Player") # Set the title of the
window
        self.win.set_icon_from_file('favicon.ico') # Set the window
icon to a web browser icon
        self.win.set_position(gtk.WIN_POS_CENTER) # Position the
window in the centre of the screen

        self.win.connect("destroy", self.close_window) # Connect the
'destroy' event to the 'CloseWindow' function, so that the app will
quit properly

        # Handle media keys under Gnome
        DBusGMainLoop(set_as_default=True)
        bus = dbus.Bus(dbus.Bus.TYPE_SESSION)
        settings = bus.get_object('org.gnome.SettingsDaemon', '/org/
gnome/SettingsDaemon') # Connect to gnome settings D-Bus
        settings.connect_to_signal("MediaPlayerKeyPressed",
self.action)

        # Create the browser widget
        gtkmozembed.set_profile_path("/tmp", "simple_browser_user") #
Set a temporary Mozilla profile (works around some bug)
        self.mozbrowser = gtkmozembed.MozEmbed() # Create the browser
widget

        # Set-up the browser widget before we display it
        self.win.add(self.mozbrowser) # Add the 'mozbrowser' widget to
the main window 'win'
        self.mozbrowser.load_url("https://www.pandora.com:443/radio/
tuner_8_2_0_2_pandora.swf") # Load Pandora
        self.mozbrowser.set_size_request(640,540) # Size arrived at
after careful trial and error
        self.mozbrowser.show() # Needed for correct size

        self.win.show_all() # Show the window

    def PlayPause(self, ):
        event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
        event.keyval = gtk.keysyms.space
        event.time = 0 # assign current time
        self.mozbrowser.grab_focus()
        self.win.emit('key_press_event', event)

    def ThumbsDown(self):
        event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
        event.keyval = gtk.keysyms.minus
        event.time = 0 # assign current time
        self.mozbrowser.grabfocus()
        self.win.emit('key_press_event', event)

    def ThumbsUp(self):
        event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
        event.keyval = gtk.keysyms.plus
        event.time = 0 # assign current time
        self.mozbrowser.grabfocus()
        self.win.emit('key_press_event', event)

    def Skip(self):
        event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
        event.keyval = gtk.keysyms.Right
        event.time = 0 # assign current time
        self.mozbrowser.grabfocus()
        self.win.emit('key_press_event', event)

    # Handles key presses
    def action(self, *keys):
        for key in keys:
            if key == "Play":
                self.PlayPause()
            elif key == "Stop":
                self.ThumbsUp()
            elif key == "Previous":
                self.ThumbsDown()
            elif key == "Next":
                self.Skip()

    def close_window(self, caller_widget):
        """Close the window and exit the app"""
        gtk.main_quit() # Close the app fully

if __name__ == "__main__":
	wrapper = Wrapper()
	gtk.main()
