The crash is happening in the destructor of the help controller when the 
other top level windows of the app have already been deleted.  You can 
workaround the problem by forcing the help controller to do its cleanup 
before the app's main frame is destroyed.  In my sample I just added a 
EVT_CLOSE event handler to the frame that looks like this:

     def OnCloseWindow(self, evt):
         del self.help
         evt.Skip()
