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"). -- Dieter
