After mongo update to 2.4.x mapreduce with inline output will fail with error 'no collection name':

mapreduce(function()

{ emit('bank', (this.spec_chips || 0) + (this.spec_locked_chips || 0)); emit('cnt', NumberLong(1)); }

, function(k, va) { var r = 0; va.forEach(function(v)

{ r += v; }

); return r; }, { updated_at:

{ $gt: 1364155200 }

, weeklong_member: true },

{ inline: 1 }

)

In mongo shell it's ok. With collection name instead of

{inline:1}

is ok.
