[wxPython] First tutorial fails

Anyone know why the first tutorial:

from wxPython.wx import *

class MyApp(wxApp):
    def OnInit(self):
        frame = wxFrame(NULL, -1, "Hello from wxPython")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

    app = MyApp(0)
    app.MainLoop()

should fail with the following message:

09:21:32 AM: Debug: c:\Projects\src\msw\app.cpp(535): 'UnregisterClass)' failed with error 0x000000584 (class still has open windows.).

Anyone know why the first tutorial:

from wxPython.wx import *

class MyApp(wxApp):
    def OnInit(self):
        frame = wxFrame(NULL, -1, "Hello from wxPython")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

    app = MyApp(0)
    app.MainLoop()

Do you really want these two lines indented?
