Good catch, this must have been in there for a while already. This check
stopped working with a certain Cocoon release, from which all our own
exceptions were wrapped inside another exception.

I've changed the check simply to use index [2]. If
DocumentReadDeniedExceptions are nested deeper, it must be for some
other cause that we probably want to display to the user.

For default, I prefer to keep the current behaviour, as it tells the
user explicitely what is wrong.
