[Zope] Power fail seems to have coddled something

[Dennis Allison]

Power fail.  Now the root and the first folder in the root won't publish
the index_html at the root and give the diagnostic

Error Type: ValueError
Error Value: unpack list of wrong size



Traceback (innermost last):

Other things seem to be intact and accessible.

Any hints as to how to proceed would be appreciated.
