[Zope-CMF] Delete trouble

Hi guys,
At the moment, with the tools-as-utilities branched merged, it's
sometimes impossible to delete a Plone site. I haven't looked too deeply
into it, and I don't have a test for it, unfortunately, but it seems
that when content has been added, we get errors like the one below. It
seems to me like in this case, a particular utility has been removed
before something that assumes it's there is deleted.
There is nothing Plone specific about this error, i.e. nowhere in Plone
that we can make changes to avoid it. We did have a similar problem in
AT's catalog multiplex despatcher which we solved by checking for
ComponentLookupErrors.
I think resolving all of these errors through re-ordering of calls and
the like could be quite tricky. It's something of a cop-out, but it's
probably easier to insert a lower level catch all for
ComponentLookupErrors in e.g. CMFCatalogAware's event handlers.
What do people think of this idea? At the moment, it's painful to do
development on Plone; I have instances in my ZODB like test, test1,
test2, test3, test4... ;-)
