This worked fine:

    def _handleMINCImageAttributesError(self, attributes, event):
        pass

and then

        self.reader = vtkMINCImageReader()
        self.reader.GetImageAttributes().AddObserver(
            vtkCommand.ErrorEvent, self._handleMINCImageAttributesError)

Good thing that the attributes object is available before the image has
been loaded.

I'll try to filter out just those bogus errors with some string matching.
