This was a Qt bug and has been fixed.
https://bugreports.qt.io/browse/QTBUG-60427

And instead of a SIGABRT there is a nice error message!

Traceback (most recent call last):
  File "bug.py", line 15, in names
    return QtQml.QQmlListProperty(str, self, self._names)
TypeError: type argument must be a sub-type of QObject
