Comment 8 for bug 930563

I also have observed this problem. `dbus-monitor --session` shows the following when I click on a menu item,

    signal sender=:1.74 -> dest=com.canonical.Unity.Panel.Service serial=207627 path=/com/canonical/Unity/Panel/Service; interface=com.canonical.Unity.Panel.Service; member=EntryActivated
       string ""
       struct {
          int32 0
          int32 0
          uint32 0
          uint32 0
       }
    method call sender=:1.74 -> dest=:1.1485 serial=207628 path=/org/ayatana/NotificationItem/nm_applet/Menu; interface=com.canonical.dbusmenu; member=EventGroup
       array [
          struct {
             int32 43153
             string "clicked"
             variant int32 0
             uint32 636178867
          }
       ]
    error sender=:1.1485 -> dest=:1.74 error_name=org.gtk.GDBus.UnmappedGError.Quark._LIBDBUSMENU_2dGLIB.Code0 reply_serial=207628
       string "The IDs supplied '[43153]' do not refer to any menu items we have"
