The cumulative incidence curve and the KM are not the same, when there are multiple outcomes. See the "etype" argument to survfit, which is used to create CI curves (?survfit.formula). For testing differences between CI curves use the cmprsk library from Gray; it can also draw curves by the survfit routine has a lot more flexibility.
