TypeError: Cannot read property 'properties' of undefined @ Object.utils.getRelatedComponent

I'm getting this when I run eslint:

/path_to_code/node_modules/eslint-plugin-react/lib/util/Components.js:298
        if (!node.properties) {
                 ^

Things seem reasonable if I change that line to instead be if (!node || !node.properties) { but that's a pretty dirty hack.

I get this error with the following JSX file:

export default const Foo = {}
Foo.Bar = class extends React.Component {
}
Foo.Bar.propTypes = {};
