If I import ErrorHandler in simulate_mice.py before I import MAUS I get a segmentation fault. Sample code

import io
import json
import MAUS         ### <<< ordering here causes Segmentation fault
import ErrorHandler ### <<< ordering here causes Segmentation fault

SIM_ARGS = None

def run():
    global SIM_ARGS
    input_file = io.StringIO(unicode(json.dumps({"mc": []})))
    my_input = MAUS.InputPyJSON(input_file)
    my_map = MAUS.MapPyGroup()
    my_map.append(MAUS.MapPyBeamMaker())  #  input beam
    my_map.append(MAUS.MapCppSimulation())  #  geant4 simulation
    my_output = MAUS.OutputPyJSON(open("simulation.out", 'w'))
    datacards = open('input.py')
    SIM_ARGS = (my_input, my_map, MAUS.ReducePyDoNothing(), my_output, datacards)

if __name__ == '__main__':
    run()
    MAUS.Go(*SIM_ARGS)
