I'd suggest the problem is down to not understanding the data structure
you are walking.  Unfortunately, I don't know its structure either but
the typical way to debug code such as this is to not *follow* a pointer
and print something it points to but to print out the value of the
pointer, i.e. the address.

This prevents failure and uncovers the first layer of the structure.
You can then determine the rules to move through to the next layer, and
so on.

If your attempt at the first layer still goes Boom! then you need to
step back one more level.
