Server-side error in with-loading example?

[moarwick]

The with-loading example works well client-side, but on hard refreshing the /forever or /about routes, it throws Cannot read property 'Component' of undefined. Component is being imported from React in those two pages. Full trace:

Research Notes:

Returning null (or nothing) from getInitialProps() cause this issue.

+1 I've run into this before, returning {} resolves the issue, but it'd be good to provide that default considering the error is not helpful.
