Cannot add >4 AWS roles to a user

[nonspecialist]

When attempting to add a fifth AWS role to a user, the tool crashes with a backtrace similar to:

$ federator user -U [email protected] add -R arn:aws:iam::123456789012:role/FederatedAdministrator -P arn:aws:iam::123456789012:saml-provider/GoogleApps
