title: Libnotify not displaying notifications when using Spork and Guard
body: <p>Libnotify was working fine on my system (Lubuntu) until I started using guard-spork.</p>
  
  <p>My Guardfile:</p>
  
  <pre><code>notification :libnotify
  
  guard 'spork', :wait =&gt; 60, :rspec_env =&gt; { 'RAILS_ENV' =&gt; 'test' } do
    # ...
  end
  
  guard 'rspec', :version =&gt; 2, :all_after_pass =&gt; false, :cli =&gt; '--drb' do
    # ...
  end
  </code></pre>
  
  <p>My Gemfile:</p>
  
  <pre><code>group :development, :test do
    gem 'rspec-rails'
  end
  
  group :test do
    gem 'rb-inotify'
    gem 'libnotify'
    gem 'spork'
    gem 'guard-spork'
    gem 'guard-rspec'
  end
  </code></pre>
  
  <p>What could I be doing wrong here? I run <code>bundle exec guard</code>, spork is working fine, my tests are all passing, but the notifications are not showing up through libnotify. I'm using latest gems.</p>
