And the expedition was a qualified success.  It turns out that
getObject has one of those nasty unadorned try: except: structures
in it.  It was masking an authorization error.  The auth error
is occuring in urestrictedTraverse, and the last lines of my traceback
are:

  File /usr/local/zope/Zope230/lib/python/OFS/Traversable.py, line 190, in unrestr
ictedTraverse
    (Object: ApplicationDefaultPermissions)
Unauthorized: 0060175400

0060175400 is the ID of the first object returned by the catalog.

Any guesses why this is happening?  I get the same result whether I'm anonymous
or logged in as a manager.

Also, anyone want to guess why getObject uses try/except?  I can't off
the top of my head think of any reason it should be there.

This is 2.3.0, I suppose I should try the new beta just for kicks...
