    Hi,

    Well, I couldn't figure out why it's happening, but I managed to isolate
    it.

    To reproduce the bug, we can run only

    nxtomomill/converter/edf/tests/test_edf2nx.py::test_edf_to_nx_converter

    IMO the issue is in the pytest.mark.parametrize call

    @pytest.mark.parametrize("progress", (None, tqdm(desc="conversion from edf")))

    Removing that line, and defining progress in the test, the segmentation
    fault doesn't occur.

    def test_edf_to_nx_converter(duplicate_data, external_path_type):
    + progress = tqdm(desc="conversion from edf") # or progress None

    So, the first I think is that the issue is in the parametrize and/or
    tqdm, but I made a little poc, and the error is not reproducible:

    ```
    @pytest.mark.parametrize("progress", (None, tqdm(desc="hola")))
    def test_poc(progress):
    if progress is not None:
    progress.total = 100
    progress.n = 20
    progress.refresh()
    assert 1==1
    ```

    So, now I suspect that the bug is in python3-nxtomomill side.
