[Zope] ZODB question - obtaining type information from known OID

I am trying to track down some write conflict errors in a Product I am working on. The event.log is telling me (for example): ConflictError: database conflict error (oid 000000000011e870, serial was 0358665aa2650baa, now 0358665a4ba78c99) I would like to find out what class of object is producing the conflict, so I can write an _p_resolveConflict function to handle the problem, but the log doesn't tell me the conflicting objects type. What is the best/easiest way to get type information from the provided OID# ? --Sean
