Repeated "Kernel died, restarting" forever
<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>
