title: Less CSS URL variable always shows server base URL before variable output
body: <p>Consider this LESS code:</p>
  
  <pre><code>#login-form-submit {
      @base-url: "/webshop/rsc/img";
      background-image: url("@{base-url}/icons/login.png");
  }
  </code></pre>
  
  <p>The output CSS is: </p>
  
  <pre><code>#login-form-submit {
      background-image: url("http://localhost:8080/webshop/rsc/css/specific//webshop/rsc/img/icons/login.png"); 
  }
  </code></pre>
  
  <p>Does anybody know why this might be happening?  If I abandon the variable and use the string directly, the CSS outputs as expected. (Without the fully qualified URL.)</p>
  
  <p>The server this is running on is jBoss EAP 5.</p>
