Comment (by nickm):

 Hm.  When I try to parse it I get ...
 {{{
 Nov 26 12:47:31.000 [warn] ID on signature on network-status vote does not
 match any declared directory source.
 Nov 26 12:47:31.000 [warn] Unable to parse networkstatus consensus
 Nov 26 12:47:31.000 [warn] Couldn't load consensus ns networkstatus from
 "/Users/nickm/.tor/cached-consensus"
 }}}

 That comes from:
 {{{
     if (!(v = networkstatus_get_voter_by_id(ns, declared_identity))) {
       log_warn(LD_DIR, "ID on signature on network-status vote does not
 match "
                "any declared directory source.");
       goto err;
     }
 }}}

 So apparently it's complaining because it got a signature on this document
 that didn't have a corresponding dir-source block.  That's pretty weird --
 there's only one signature on it, and that signature should be from moria.
 But apparently moria is omitting its own dir-source block in the
 consensus:

 I think that's the problem.  But now to find out why it happens!
