Exception Type: System.Exception Message: User profile returned from SharePoint as Nothing for UserID 'S-1-5-21-59715478-2608859843-3034944815-2139'. Data: System.Collections.ListDictionaryInternal TargetSite: NULL HelpLink: NULL Source: NULL

Answer 1

That corresponds to a user in Active Directory who has either been removed from a group or has been disabled. There really isn't a "fix" for this. Just make sure that you don't leave site collections or owners as null when you do this.

Another reason why documentation and Architecture are very important for SharePoint! :-)
