Issue #7106: GIMP 2.99.6 Python Script Fatal Error. 

All objects of subclass GtkWindow are special as they are actually owned
by GTK which keeps a list of all top-level windows. So we cannot
actually give ownership to the caller. With GObject Introspection in
particular, it will mean a double-free of the dialog object (by GTK,
then by the GI layer).

See also gobject-introspection#394.
