crash in QAccessibleEvent::uniqueId() on MacOS 10.12.1

This issue is somehow similar to QTBUG-39008. The 3 top calls (leading to the crash, see further), are the same.
The difference, is that the problem occurs in 5.6.1 and not in 5.6.0
And I see that the 4th call from the top, is:
QAbstractItemView::setSelectionModel
which was changed from 5.6.0 to 5.6.1 (but also from 5.6.1 to 5.6.2)
I don't think the problem is directly in QAbstractItemView::setSelectionModel but the change awakes another bug, I guess QTBUG-39008

This is a problem that some users are reporting (I get the stack trace). I have no time to create a test application.
But I write this report, thinking it can be useful to solve QTBUG-39008
