Scott Moser 5f358050ce walker_callback: fix traceback on empty payload.
A previous commit of mine here tried to apply a trivial fix
to avoid a warning on empty content type.  Instead, it made
the empty content type call a handler which did not exist.

This instead logs warning on unknown non-empty payload.
It logs debug on empty payload.
