It was a class shape issue. The second subcomponent had code to set
the ivar in the main component, and the main component's #children
referred to it as well, but the ivar wasn't present in the class.

I don't know what Squeak does with ivars that are referenced but don't
exist, but it sure leads to funny results :)
