Ah I understand it now. You get an assertion error in the constructor 
before the
allow_destruct bool can be set. So in the destructor you get another 
error because the
allow_destruct isn't set. So the first error is a bug, the second can 
be blamed on python
allowing dynamic types. We could prevent it by assigning allow_destruct 
earlier but it
shouldn't be a problem. I think it is fixed here 

The binding for czmq is updated as well. Just pull from the latest
