Hello,

I have a creepy problem.

I need to (un)pickle a GdkPixbuf.Pixbuf object because it is
shared/transfered between Processes via the multiprocessing.Queue
object.

But the object is "modfied" while the pickle process. Before it is like
this
<GdkPixbuf.Pixbuf object at 0x7f8b9e9cfb88 (GdkPixbuf at 0x563b61725c60)>

after pickeling it is like this
<GdkPixbuf.Pixbuf object at 0x7f8b9e9eaea0 (uninitialized at 0x(nil))>

I opened a StackOverflow question for it with a minimal working example.
