Interactive python3 segfaults in container

[MustafaMustafa]

Hi,

python3 segfaults in interactive mode inside a dedalus container. You can fix that by uninstalling gcc readline and installing the gnu one. I did that in our downstream image dockerfile, but you might want to fix it the base image.

To test try to import anything in python3 interactive mode inside a container.

Possible solution, add the following in the Dockerfile:
RUN pip3 uninstall readline --yes && pip3 install gnureadline

Thanks a lot of all the great work, Dedalus has been very helpful for us.
