Comment 2 for bug 189783

Should such a view be part of zope.app.intid?
It has a populate view, but that doesn't traverse the site tree.
In my case, I encountered the problem indirectly when adding another package so it took some time to track down what was happening because I initially suspected the the new package was at fault.
Anyhow, this problem can be subtle - which is why I raised this issue - too save others tripping up on it.
