I ran in to this problem as well after a recent upgrade to 13.10. Removing the pertinent calendar config file from ~/.config/evolution/sources/ fixed the issue for me. There are likely multiple configuration files in that directory so you will have to determine which specific calendar is causing the problem for you.
