I was having this issue too, looks like it was fixed on the jedi side in https://github.com/davidhalter/jedi/issues/1490 -- they haven't issued a new release recently, but the issue is resolved if you use the package directly from master:

pip3 install -e git://github.com/davidhalter/jedi.git#egg=jedi
