I would catch the error and enter a debugger to analyse the "o" above.

With "pdb" (the Python Debugger, part of Python),
this could look like:

     try: dump(state)
     except: import pdb; pdb.set_trace()

Zope will then enter the debugger when the error happens.

You must run Zope in the foreground for this to work
(otherwise, you do not have a chance to interact with "pdb").
