[Zope] Problem: Document Library 1.0b1 + Zope 2.4.2

[Richard Hewison]

We have had a similar problem today, with Document Library 1.0b2 and the =
upgrade of Zope 2.4.2 (from 2.4.1). The errors we get when trying to view =
our library index_html DTML method are as follows:

Traceback (innermost last):

We've just added the update to the Library (to b3) and it still isn't =
working,  (unless there's something we've done wrong). Obviously this now =
means that our document library is broken :-(
