Adding a v confusing error message which my colleague just hit (not exactly the same as this, but thought it wasn't worth a whole new issue):

```

In [10]: xr.DataArray( ...: data=1, ...: coords={ ...: 'test':[1]#, ...: }, ...: dims=['test'] ...: )

KeyError Traceback (most recent call last) <ipython-input-10-41a019d49aae> in <module> 4 'test':[1]#, 5 }, ----> 6 dims=['test'] 7 )

KeyError: 'test' ```

...nothing to do with the test entry, it's that data is a scalar
