Unfortunately I can't associate this with a specific input yet because it's only occurring on a CI server, but this is using eslint-plugin-react 3.11.3 and babel-eslint 5.0.0-beta6.

This was caused by something like:

        <div className={`strong fill-lighten0 pad1 contain small icon ${typeLabel[type].icon}`}>
          {typeLabel[type].displayName}
       </div>

Pretty sure having an object with a displayName property is confusing eslint-plugin-react.

I was not able to reproduce the crash, but I added an additional check that should prevent this case.
