[Zope-dev] Could not load state?

Hi, I've started seeing errors like this: ------ 2001-02-27T11:18:34 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\00 0\021\275\220' Traceback (innermost last): File E:\Zope\23C76D~1.1B1\lib\python\ZODB\Connection.py, line 477, in setstate AttributeError: 'None' object has no attribute 'load' ...popping up from time to time. I think they're coming from a product we've written, but beyond that I have no idea what's going on. How would I begin to dig? Is there any way I can find out the id of the object that OID corresponds to? cheers, Chris
