title: Error parsing yaml file: mapping values are not allowed here
body: <p>I want to upload an app to Google App Engine:</p>
  
  <p>I get this</p>
  
  <pre><code>Error parsing yaml file:
  mapping values are not allowed here
    in "/home/antonio/Desktop/ATI/climate-change/app.yaml", line 2, column 8 
  </code></pre>
  
  <p>When running</p>
  
  <pre><code>./appcfg.py update /home/antonio/Desktop/ATI/climate-change
  </code></pre>
  
  <p>with this app.yaml file:</p>
  
  <pre><code>application:climate-change
  version: 1
  runtime: python27
  api_version: 1
  threadsafe: true
  
  handlers:
  - url: /.*
    script: helloworld.app
  </code></pre>
  
  <p>line 2, column 8 corresponds to the version line. What is wrong here? Btw, I'm using Ubuntu 12.04 here. </p>
