[Zope] Zope Release 2.4.1 possible bug?

Hello there, is it possible that there is a little bug in Zope release 2.4.1? restrictedTraverse fails in some situations with the message: Error Type: NameError Error Value: global name 'has' is not defined For example it doesn't work at all with "absolute" paths like ("", "subdir", "somewhere")... Seams as there was a has=hasattr forgotten in the unrestrictedTraversable-Method in lib/python/OFS/traversable.py What to do? Regards, Holger
