App freezes if session variable value is too large

[bwobst]

Example:

var apiKey = [you'll need to use yours to repro: https://secure.mashery.com/login/edmunds.mashery.com/];
var apiEndPoint = "https://api.edmunds.com/api/vehicle/v2/makes?fmt=json&api_key=" + apiKey;

Meteor.http.get(apiEndPoint,
      function(error, result) {

        if (!error && result.statusCode === 200) {

          // This breaks JetSetter.  I think it's because the value of the variable is too large:
          // var res = JSON.parse(result.content);
          // makes = res.makes;
          // console.log(res.makes); // array of 62 objects
          // Session.set('jsonResMakes', makes);

          // This works great
          var test = [{niceName: 'a'}, {niceName: 'b'}, {niceName: 'c'}];
          Session.set('jsonResMakes', test);

        } else {
          console.log('didn\'t work...');
        }

      });
