Relate and label don't work in batch mode in case of updating existing node

[ohord]

This works fine:

    var someId = 1;
    var userJson = {some:"user"};
    var txn = db.batch();
    var user = txn.save(userJson);
    user.label("User");
    txn.relate(user,'has',someId);
    txn.commit(function(){})

this also works fine:

    var someId = 1;
    var userJson = {some:"user",id:2};  // Existing id in the database
    var txn = db.batch();
    var user = txn.save(userJson);
    txn.commit(function(){})

but this doesn't work:

    var someId = 1;
    var userJson = {some:"user",id:2}; 
    var txn = db.batch();
    var user = txn.save(userJson);
    user.label("User");
    txn.relate(user,'has',someId);
    txn.commit(function(){})

Error is following: Illegal character in path at index 2: ./{2}/labels
