title: graphviz/dot crash (turned out to be caused by faulty installation)
body: <p>I'm trying to use the GraphViz tools to generate some dependency graphs but I'm having zero luck getting dot to export images. SVG works fine, but anything else (jpeg, gif, png) cause dot to crash.</p>
  
  <p>Here's my graph:</p>
  
  <pre><code>digraph test {
   main -&gt; parse -&gt; execute;
   main -&gt; init;
   main -&gt; cleanup;
   execute -&gt; make_string;
   execute -&gt; printf
   init -&gt; make_string;
   main -&gt; printf;
   execute -&gt; compare;
  }
  </code></pre>
  
  <p>Here's the command-line that works (for svg):</p>
  
  <pre><code>dot test.dot -Tsvg -o test.svg
  </code></pre>
  
  <p>Here are the command lines that cause a crash:</p>
  
  <pre><code>dot test.dot -Tjpg -o test.jpg
  dot test.dot -Tjpeg -o test.jpeg
  dot test.dot -Tpng -o test.png
  </code></pre>
  
  <p>Am I missing something obvious?</p>
  
  <p>Thanks,</p>
  
  <p>(Note this is on WinXP 32-bit using the 2.24 graphviz package).</p>
