  <p>I am on Ubuntu 13.04, 32 bit, linux kernel 3.8.0-31-generic</p>
  
  <p>I tried uninstalling atlas as mentioned <a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=607244" rel="nofollow">here</a> but could not find libatlas3gf-base so removed fgfs-atlas instead but that did not work. </p>
