Not sure, but I do know that there are some other things ErrorView
could do. An exception view is just a multiadapter for (<exception
instance>, <request>) and depending on your exception instance (say, a
KeyError), you'll end up with very little information about your
situation. For instance, the ".context" of this view certainly won't
have any idea of location (in the ILocation sense).

I'd sugest that, at the very least, an ErrorView instance have a .site
attribute taken from zope.app.component.hooks.getSite() or a more
appropriate equivalent.
