A ipython upgrade solves this (somewhat). Jedi upgrade makes the
traceback a bit nicer then.
After upgrading I still get an error message, but the sessions recovers
itself.
Upgrading ipython and jedi is subject to

Here is the remaining traceback, still strange, but only a bit annoying,
as at least the session is kept active:

an isolated upgrade to 0.18 probably won't fly.
And indeed, jedi is used in ipython, not only in jupyter. Perhaps one
can update only ipython, and leave jupyter for later?
I don't know.

All rather strange to me. To be clear. I'm not using jupyter, I'm just on the
shell.

The jedi upgrade (to 0.18.0) does not fix the error, but does change the log:

Actually the error is reproducible:
def foo(): return 2
foo()
foo()
What makes it crash is hitting TAB after opening the parenthesis and then
completing it and hitting enter.

A Jupyter upgrade is in https://trac.sagemath.org/ticket/31280 - which needs
some help

it looks like https://github.com/davidhalter/jedi/issues/1615
and our version of jedi is older than the fix there.
Upgrade jedi (if this is possible without a full ipython/jupyter
upgrade, don't know) ?

Dear all,
sage crashes once in a while hard with some strange error.
Does anyone know what is going on? This is somewhat new. Not reproducible.
Happened to me maybe 3 or 4 times now at various occasions.
