Jupyter lab does not start up
When executing
jupyter lab
or
jupyter-lab
I get a stack trace from Python:
>>> START
Traceback (most recent call last):

get
value = obj._trait_values[self.name]
~~~~~~~~~~~~~~~~~^^^^^^^^^^^
KeyError: 'core_config'
During handling of the above exception, another exception occurred:

This looks a little like the distributed code isn't built for deployment but
for building the final package (the `staging` part of the above error).
Also, the package seems to dump code all over `/usr/lib/python3/dist-packages`,
for example
>>> START
...
/usr/lib/python3/dist-packages/docs/source
/usr/lib/python3/dist-packages/docs/source/conf.py
/usr/lib/python3/dist-packages/examples
/usr/lib/python3/dist-packages/examples/app
/usr/lib/python3/dist-packages/examples/app/main.py
...
/usr/lib/python3/dist-packages/packages
/usr/lib/python3/dist-packages/packages/extensionmanager-extension
/usr/lib/python3/dist-packages/packages/extensionmanager-extension/examples
/usr/lib/python3/dist-packages/packages/extensionmanager-
extension/examples/listings
/usr/lib/python3/dist-packages/packages/extensionmanager-
extension/examples/listings/main.py
...
/usr/lib/python3/dist-packages/scripts
/usr/lib/python3/dist-packages/scripts/i18n_check.py
<<< END
That also seems to be a mistake. Perhaps the installation into the package
distribution is messed up?
