PyGTk圖片不在菜單中顯示

Question

最近我開始學習pygtk。作爲一項練習，我打算建立一個小型的閱讀器。目前我有以下（工作）代碼：

#!/usr/bin/env python 

import pygtk 
pygtk.require('2.0') 
import gtk 

class FeedbarWindow(): 
    prop_file = 'feedbar.prop' #Properties File 
    menu_bar_ui = """ 
        <ui> 
         <menubar name="MenuBar"> 
          <menu action="Feeds"> 
           <menuitem action="RefreshAll"/> 
           <menuitem action="MarkAllAsRead"/> 
          </menu> 
          <menu action="About" name="AboutMenu"> 
           <menuitem action="Version"/> 
           <menuitem action="ShowAbout"/> 
          </menu> 
         </menubar> 
        </ui> 
        """ 

    #INITIALIZERS 
    def __init__(self): 
     """ Initialize all the components in the Feedbar GUI """ 
     #MAIN WINDOW 
     self.window = gtk.Window() 
     self.window.set_title("Feedbar") 
     self.window.set_size_request(500, 400) 
     self.window.set_position(gtk.WIN_POS_CENTER) 
     self.window.connect("destroy", self.window_destroy) 
     self.window.connect("delete-event", self.window_delete_event) 
     #MAIN VERTICAL BOX 
     self.main_vbox = gtk.VBox(False, 2) 
     self.window.add(self.main_vbox) 
     #ACTION GROUP (FOR MAIN MENU) 
     self.action_group = gtk.ActionGroup("MenuBarActionGroup") 
     self.action_group.add_actions([

     self.window.add_accel_group(accel_group)

     self.ui_manager.add_ui_from_string(self.menu_bar_ui) 
     #MENUBAR 
     self.menu_bar = self.ui_manager.get_widget("/MenuBar") 
     self.main_vbox.pack_start(self.menu_bar, expand=False, fill=False) 
     #SHOW COMPONENTS

一切工作正常，但菜單中的圖片沒有顯示出來。你有任何提示嗎？它是一個程序員的失明類型的東西，我正在失去某種方式？

圖標顯示在我的菜單中，確保您啓用了菜單圖標。 來自終端：gconftool-2 --type bool --set /desktop/gnome/interface/menus_have_icons True
