Error to precompile assets with rake 10.1.0

Question

I was using rake 10.0.4 and I've upgraded to 10.1.0, but now when I deploy to my staging server it throws me:

rake aborted!

(See full trace by running task with --trace)

My Rakefile doesn't have anything special:

#!/usr/bin/env rake
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require File.expand_path('../config/application', __FILE__)

MyApp::Application.load_tasks

If I downgrade to 10.0.4 again, it works fine. Any clue?

It's a known problem with the seedbank gem. The latest version of seedbank (0.2.1) still has the issue so the suggestion in the seedback issues is to use the version from github in your Gemfile:

gem 'seedbank', github: 'james2m/seedbank'
