Beginner GTK question

[dashawn888]

I have a simple page that I want to display a menu and toolbar.  I
have followed the tutorials and have made some customizations to the
basic code snippet found at

http://www.pygtk.org/pygtk2tutorial/examples/uimanager.py

However my customized code does not display the menu bar.  It displays
the toolbar though.  The terminal output is

--------------------------------------------------------------------------------
gui.py:79: GtkWarning: Quit: missing action
  menubar = uimanager.get_widget('/MenuBar')
--------------------------------------------------------------------------------

Line 79 is this

menubar = uimanager.get_widget('/MenuBar')

Thank you for any help in advanced.

Here is the code
