Update of /cvs-repository/Zope3/src/zodb
In directory cvs.zope.org:/tmp/cvs-serv575/src/zodb

Modified Files:
	serialize.py 
Log Message:
There's a bug in ZODB 4. Sometimes, persistent references aren't being
constructed correctly.  The arguments for __new__ are being set to
None when they shouldn't be.  This doesn't happen all the time.  :/

I've added a work-around.  If the construction of a ghost failes with
a type error, we will fall back to the more expensive load method.

This is a band-aid.  I don't want to chase this bug down, because we
intend to replace ZODB 4 with ZODB 3.3 and there are more pressing
things to do.
