Thanks for the report, I'm marking this as a bug.

The issue is with these lines in IndexVariable.concat. We defer to pandas for concatenating coordinate labels, but pandas doesn't handle structured dtypes properly (it converts them to dtype=object). This is part of why we have PandasIndexAdapter.

It seems like we now need some more complex logic for toggling between pandas Index.append() and numpy.concatenate, based on the Index dtypes.
