This is the same exception as in bug 204815, but a different case, from a later version. The sample from the bug still works fine. Would be nice to have a new test case to reproduce this exception. It shows the layout structure blew up completely by moving (or adding) a component.

Actually the exception here indicates the same problem that in later versions is detected on a different place.
