title: ERROR: ld.so: object LD_PRELOAD cannot be preloaded: ignored
body: <p>I am using ubuntu 12.04. Every time I start my bash terminal and every time when I finish typing a command(and press enter) , I get this message: </p>
  
  <blockquote>
    <p>ERROR: ld.so: object '/usr/lib/liblunar-calendar-preload.so' from
    LD_PRELOAD cannot be preloaded: ignored.</p>
  </blockquote>
  
  <p>It is weird.
  So what is the environment variable LD_PRELOAD used for? And what is the going on behind the scene?</p>
  
  <p>Thanks.</p>
