It looks like it is possible that some of the data may be corrupted. In this thread people are pushing the person to use SQL to directly delete some of the owners off of the activity - http://social.microsoft.com/Forums/en/crmdeployment/thread/d82cedee-e24e-4abc-9ec6-41306b89ed3b

This is only a possibility if you are using the on-premise model of Dynamics CRM 2011.
