This looks like you connected up an incompatible reader to the input of the 
doubleThreshold. Could you explain in more detail what you did here?

I have the same problem connecting DICOM reader output to Double threshold input

Same problem here... DICOM reader and double threshold...

I debugged a bit, and it seems that the module is loading set_input function with a wide variety of inputStream things... Nones, Meta data, ...

For the moment I worked around the issue replacing set_input with the following function:

    def set_input(self, idx, inputStream):
        try:
            self._imageThreshold.SetInput(inputStream)
        except TypeError:
            return
        # get scalar bounds
        minv, maxv = inputStream.GetScalarRange()

However, Right now the tool is not able to properly handle exceptions caused by wrong input types.

Similar work around can be practised with other tools
