Inlined documentation reveals private implementors

For example, NaiveSearcher on the clone page: http://doc.rust-lang.org/std/clone/trait.Clone.html

Another example: RcBoxPtr on rc::Weak: http://doc.rust-lang.org/std/rc/struct.Weak.html

Edit: This example no longer reproduces, but @alexcrichton's original one does.

Triage: still a problem

I'm having a go at fixing this, but I have trouble reproducing it. Does anyone have an example of this problem outside of the standard library?
