The murky bit with this solution is that a defaultView adapter has to
be registered for (IException, IHTTPRequest), as the error view lookup
expects that in zopepublication.py line 296, otherwise a standard 500
error is returned to the client.

Isn't default view name a browser-views-only concept?

Anyway, I added this to the config, but I doubt this is the correct
solution:

  <defaultView
      for="zope.interface.common.interfaces.IException"
      type="zope.publisher.interfaces.http.IHTTPRequest"
      name="GET"
      />

Any ideas?
