title: Python locale error: unsupported locale setting
body: <p>Why do I get the following error when doing this in python:</p>
  
  <pre><code>&gt;&gt;&gt; import locale
  &gt;&gt;&gt; print str( locale.getlocale() )
  (None, None)
  &gt;&gt;&gt; locale.setlocale(locale.LC_ALL, 'de_DE')
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "/usr/lib/python2.7/locale.py", line 531, in setlocale
      return _setlocale(category, locale)
  locale.Error: unsupported locale setting
  </code></pre>
  
  <p>This works with other locales like fr or nl as well. I'm using Ubuntu 11.04.</p>
  
  <p>Update: Doing the following did not yield anything:</p>
  
  <pre class="lang-none prettyprint-override"><code>dpkg-reconfigure locales
