KeyError on list_tasks #1234
Description
Description
OpenML crashes during list_tasks call.
It was working correctly 1 week ago.
I first noticed the error on March 25th when running a script to generate a task metadata file locally.
I've reproduced the error both on an ubuntu EC2 instance and locally on my Mac laptop.

import openml
tasks = openml.tasks.list_tasks()Exception

KeyError: 0
During handling of the above exception, another exception occurred:
