The view looks like this:

function(doc) {
  if ('product' === doc.collection && doc.producers) {
    doc.producers.forEach(function(each) {
      emit(each, doc);
    });
  }
}

I'm not sure how to get the exact document that this failed out of the db.

This is on the current master.

[jchris]

actually maybe there is a random document where doc.producers exists but is not an array

[jchris]

we should add forEach tests to the Android JS tests
