What about:
- the QObject's parent? Is it set with setParent(other->parent()) or set to nullptr?
- the QObject's thread? Is it guaranteed that it is the same thread that creates the copy?
- the QObject's children? Who is going to own them and when are they deleted?
- the QObject's connections? Will all copies emit the same signals, will all copies have their slots called?

...or just look at the Qt documentation on QObject, at http://doc.qt.io/qt-5/qobject.html#no-copy-constructor.

Best Regards / Mit freundlichen Grüßen
