The above exception was the direct cause of the following exception:

Traceback (most recent call last):

How can we reproduce this issue?

1. Create a cancerous amount of roles (50)
2. Give all roles to desired user
3. Get userinfo from that user

Oh boy. Rather than attempt embed pagination, I think there's a certain point where it's acceptable to tell the server owner we wont support displaying that many roles in user info.
