This is moderately reproduceable against my client node.  Hacking the code a bit, I see that when it occurs, `op` (at least sometimes) is:

{{{
{u'mode': u'MODE_READ',
 u'status': u'Sending 1 initial queries',
 u'storage-index-string': u'vfl23nfdydohpriimglb7dynje',
 u'total-size': u'-NA-',
 u'type': u'mapupdate'}
}}}
