Update of /cvs-repository/Zope3/src/ZODB/zodb4
In directory cvs.zope.org:/tmp/cvs-serv5003
Relaxed the prickling error detection to handle all errors.
If an error occurs while unpickling records, a message will be logged
and the affected records are skipped.

+If errors looked something like:
+ "('object.__new__(SomeClass) is not safe, use
+ persistent.Persistent.__new__()', <function _reconstructor at
+ 0x4015ccdc>, (<class 'somemodule.SomeClass'>, <type 'object'>,
+then the error arises from data records for objects whos classes
+changed from being non-persistent to being persistent.
+If other errors were reported, it would be a good idea to ask about
+them on zope3-dev.
+In any case, keep your original data file in case you decide to rerun
