H5py store list of list of strings
<p>Is there a possibility in h5py to create a dataset which consists of lists of strings. I tried to create a nested datatype of variable length, but this results in segmentation fault in my python interpreter.    </p>

<pre><code>def create_dataset(h5py_file):
    data = [['I', 'am', 'a', 'sentecne'], ['another', 'sentence']]
    string_dt = h5py.special_dtype(vlen=str)
    nested_dt = h5py.special_dtype(vlen=string_dt)
    h5py_file.create_dataset("sentences", data=data, dtype = nested_dt)
</code></pre>
