title: Converting GTK 1.2 glade XML file to something glade can now read
body: <p>In <a href="https://sourceforge.net/projects/gnopstree/" rel="nofollow">old project</a> I wrote circa 2000 I have a <a href="https://sourceforge.net/p/gnopstree/code/ci/master/tree/gnopstree.glade" rel="nofollow">glade file</a> that I would like to convert to something glade can now read, and I will use in PyGtk. I have scoured SO for similar questions and see things for the code changes, but I am just interested right now in converting the glade file. </p>
  
  <p>When I run <em>gtk-builder-convert</em> I get Python traceback:  </p>
  
  <pre><code>Traceback (most recent call last):
    File "/usr/bin/gtk-builder-convert", line 799, in &lt;module&gt;

  <p>which is indeed true. The file starts: </p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;GTK-Interface&gt;
  </code></pre>
  
  <p>Suggestions? </p>
