I just tried adding my iCloud account to my girlfriends MacBook Pro. Her iCal has been working just fine, and we both have Mac OS X 10.8.
When I open iCal and see my calendars added there, it still comes up with the same error (CalDAVAccountRefreshQueueableOperation). Her calendars still working as always...
Has no one experienced the same?
