title: Repeated "Kernel died, restarting" forever
body: <p>When I attempt to run</p>
  
  <pre><code>$ jupyter qtconsole
  </code></pre>
  
  <p>The console shows up, with the message</p>
  
  <pre><code>Kernel died, restarting
  ________________________
  Kernel died, restarting
  ________________________
  Kernel died, restarting
  ________________________
  Kernel died, restarting
  ________________________
  Kernel died, restarting
  ________________________
  </code></pre>
  
  <p>Which continues.</p>
  
  <p>Trying <code>$ jupyter qtconsole --debug</code> didn't print anything else, and neither has adding</p>
  
  <pre><code>c.Application.log_level = 0
  c.Session.debug = True
  </code></pre>
  
  <p>into <code>$USERHOME/.jupyter/jupyter_qtconsole_config.py</code></p>
  
  <p>Also, I found nothing in <code>$USERHOME/.ipython/profile_default/log/</code> and the other directories around there.</p>
  
  <p>Nothing has changed in my configuration since last time I started up <code>jupyter-qtconsole</code>.</p>
  
  <p>How can I at least find out what's going wrong with the kernel? Surely there is some option in Jupyter to get the kernel's STDERR output to see what exception had upset it?</p>
