[Zope] Broken object; how can I find it?

[Bjorn Stabell]

Upon startup I get:

2001-10-08T16:30:08 PROBLEM(100) ZODB Could not import class 'ExoImage'
from module 'Products.ExoTravel.ExoDocument'

However, I don't know where this object is.  What's the easiest way to
find it?  (want to remove it)

Bye,
