title: Evolus Pencil export page as pdf does not work on Windows
body: <p>I am running Firefox version 31.0, did install pencil evolus (firefox extension).</p>
  
  <p>When I try to export a page to png or pdf I bump into a stall export dialog forever or sometimes it shuts down without exporting.</p>
