title: Bower hanging when installing dependencies on Ubuntu
body: <p>I'm trying to install a bunch of dependencies using Bower on Ubuntu 14.04. The installation hangs at a semi random point (one of jQuery, closure-library or closure compiler). Versions are below, along with the bower.json (anonymised).</p>
  
  <p>Node v0.10.35<br>
  NPM v1.4.28<br>
  Bower v1.3.12</p>
  
  <p>bower.json</p>
  
  <pre><code>{

    }
  }
  </code></pre>
  
  <p>Can anyone spot anything wrong with the <code>bower.json</code>, or know of any incompatibilities between bower and Ubuntu with these versions?</p>
  
  <p>Sample line from <code>bower install</code> output at a point where it hangs (as mentioned, the exact point it hangs changes each time, though it appears to happen on <code>resolved</code> most of the time).</p>

  bower fallback#v2  resolved https://github.com/dolox/fallback.git#0568407bc2
