@JamesSample excellent work confirming the limited scope.

I am quite sure that the issue is with this line: https://github.com/pydata/xarray/blob/v0.9.1/xarray/core/variable.py#L375-L376

dims = tuple(dim for k, dim in zip(key, self.dims) if not isinstance(k, (int, np.integer)))

When you run the test case I added in #1184, you will see that, inside __getitem__, key is a tuple with an empty array inside (key = (np.array(0, dtype=np.int64),)).

With that value, isinstance(key[0], (int, np.integer)) is False on 64 bit Windows and so dims=('time',), which has length 1.

But values = self._indexable_data[key] gives a zero-dimension array, such that values.ndim == 0...

I am unable to tell which of the two sides of the assertion expression is unexpected...
