Comment 2 for bug 123532

The patch applies cleanly to the zope.copypastemove trunk, but the test fails for reasons unrelated to the reported bug, as it depends on being able to import zope.app.container.sample, which is no longer a testing dependency. Likely we just need to write a dumb mock container inline in the test (which I would write as a unit test, but that is a de gustibus point).
