Abort trap: 6¶

The Gemfile I'm using

source 'https://rubygems.org'

gem 'rails', '3.2.13'
gem 'bootstrap-sass'
gem "font-awesome-rails"
gem 'jquery-datatables-rails', git: 'https://github.com/rweng/jquery-datatables-rails.git'
gem 'jquery-rails'

gem 'settingslogic'

gem 'rugged'
gem 'coderay'

gem 'capistrano'
gem 'capistrano-ext'
gem 'rvm-capistrano'

group :development, :test do
gem 'sqlite3'
gem "jasmine-headless-webkit", :require => false
end

group :development do
#gem 'pry'
end

group :test do
gem 'rspec-rails'
gem 'capybara'
#gem 'selenium-webdriver'
end

group :assets do
gem 'sass-rails', '> 3.2.3'
gem 'coffee-rails', '> 3.2.1'
gem 'uglifier', '>= 1.0.3'
end

group :production do
gem 'mysql2'
gem 'unicorn'
end

Can anybody help to identify if this is a ruby bug or a gem bug?
