Thanks, I agree this looks like a bug.

One oddity is that by supplying dtype="u8" I see the assignment having no effect:

```

In [18]: import xarray ...: import numpy ...: da = xarray.DataArray(numpy.array([0,1], dtype="u8")) ...: da[0] = numpy.nan ...: print(da) <xarray.DataArray (dim_0: 2)> array([0, 1], dtype=uint64) Dimensions without coordinates: dim_0 ```

I see the same result without the dtype arg.
