Launching "jupyter console" or starting a notebook kernel (either python2 or python3) fail. Please see attached logs.
Running ipython or ipython2 directly works as expected.

Additional info:
* package version(s)
jupyter_console 5.2.0-2
jupyter-notebook 5.3.0-4
ipython 6.5.0-2
ipython2 5.8.0-1
This task depends upon

Sorry, jupyter et al are in [community] so project should be "Community packages" instead.

The cause seems to be python-tornado >= 5:

jupyter is working again by updating python-ipykernel to the last version 4.8.2.
The update to 4.8.2 is easy, just updating the pkgver, although I didn't test with python2.
Can you please update the package in the official repo?

I've updated python-ipykernel to the version 4.8.2
as a result spyder3 and Jupyter are working.

So it seems that this update fix the bug.
