Warning route-recognizer

I need some help here..

Just updated my ember-cli to 0.1.9 version and the only problem is this warning:

Warning: ignoring input sourcemap for bower_components/route-recognizer/dist/route-recognizer.js because ENOENT, no such file or directory '/Users/Zaca/Eyenetra/portal/tmp/tree_merger-tmp_dest_dir-http://ift.tt/18pmNxT'

Here's my call to this addon on brocfile.js:

//brocfile.js
(...)
app.import('bower_components/moment/moment.js');

app.import({development: 'bower_components/route-recognizer/dist/route-recognizer.js'});
app.import({development: 'bower_components/FakeXMLHttpRequest/fake_xml_http_request.js'});
app.import({development: 'bower_components/pretender/pretender.js'});

module.exports = app.toTree();

This happens when I build my project for tests and for local server.

Any ideas?

Thanks for the help! o/
