    It looks like you might have a reference count unbalance on a
widget (or 5) in your program, or a corrupted stack.

essentially what I think is happening is that GTK+ is trying to
destroy widgets/objects that are either already destroyed/unreffed
or in some corrupted memory region of your program.
