[wxPython] Problems with Enable/Disable on wxMenuItem

wxPython Users

Hi,
I'm trying to Enable/Disable a MenuItem (depending on application state), however I keep getting a 'core dump'.

The following example produces the same result.
Any hints.

PS: Use Python 2.0, wxPython 2.2.1 / wxPython 2.2.2

********************************
#
from wxPython.wx import *

class MyParentFrame(wxMDIParentFrame):
    def __init__(self):
        wxMDIParentFrame.__init__(self, None, -1, "Test", size=(600,400))

        menu = wxMenu()
        submenu = wxMenu()
        self.menuitem = wxMenuItem(NULL, 5001, "Child1")
        submenu.AppendItem(self.menuitem)
        menu.AppendMenu(5002, "Super", submenu)
        menu.AppendSeparator()
        menu.Append(5003, "E&xit")
        
        menubar = wxMenuBar()
        menubar.Append(menu, "&File")
        self.SetMenuBar(menubar)

#------------

class MyApp(wxApp):
    def OnInit(self):
        self.frame = MyParentFrame()
        self.frame.Show(true)
        self.SetTopWindow(self.frame)
        return true

app = MyApp(0)
app.frame.menuitem.Enable(0)
app.MainLoop()

Change NULL to submenu and it will work.

        submenu.AppendItem(self.menuitem)
        menu.AppendMenu(5002, "Super", submenu)
        menu.AppendSeparator()
        menu.Append(5003, "E&xit")

        self.frame.Show(true)
        self.SetTopWindow(self.frame)
        return true

app = MyApp(0)
app.frame.menuitem.Enable(0)
app.MainLoop()
