Repeated "Kernel died, restarting" forever

Question

When I attempt to run

$ jupyter qtconsole

The console shows up, with the message

Kernel died, restarting
________________________
Kernel died, restarting
________________________
Kernel died, restarting
________________________
Kernel died, restarting
________________________
Kernel died, restarting
________________________

Which continues.

Trying $ jupyter qtconsole --debug didn't print anything else, and neither has adding

c.Application.log_level = 0
c.Session.debug = True

into $USERHOME/.jupyter/jupyter_qtconsole_config.py

Also, I found nothing in $USERHOME/.ipython/profile_default/log/ and the other directories around there.

Nothing has changed in my configuration since last time I started up jupyter-qtconsole.

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?
