TypeError: Cannot read property 'delegate' of null at ExRouter.componentWillUnmount

[seantempesta]

I'm hitting an exception if I rapidly switch between routes in the iOS Simulator. Looks like it's in ExRouter.js (lines 197-201):

    componentWillUnmount() {
        if (this === Actions.currentRouter.delegate) {
            Actions.currentRouter = null;
        }
    }

The component is checking currentRouter for this delegate property, but it's already null. Has anyone else hit this issue? I guess the problem could be fixed by checking if it's already null?

I don't really know how to repro the issue as it happens randomly when I'm clicking around really fast in my app.

Should be ok with latest version.
