Follow-up Comment #2, bug #58403 (project octave):

Do you know why `invokeMethod` fails?
The qt documentation for that method states:
https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod
> Returns false if there is no such member or the parameters did not match.

Could it be that `invokeMethod` is called before "slotFinalize" is installed?
If that is the case, is there a way to make sure that slot is installed early
enough?
