Gdkpixbuf.pixbufdestroynotify - Notimplementederror - Python Gtk3

I am trying to use GdkPixbuf.Pixbuf.new_from_data() as shown in gtk 2.x and I am passing 7 arguments. But it gives me an error that I need to pass 9 arguments. What I am doing now

Solution 1:

In PyGObject you shouldn't have to deal with DestroyNotify functions. If there is one exposed in the API, then this is a bug. You should report it to bugzilla.gnome.org.
