[R] Survreg(), Surv() and interval-censored data

Can survreg() handle interval-censored data like the documentation says? I ask because the command:

     survreg(Surv(start, stop, event) ~ 1, data = heart)

fails with the error message

     Invalid survival type

yet the documentation for Surv() states:

     "Presently, the only methods allowing interval censored data are
      the parametric models computed by 'survreg'"

Any pointers as to what I'm missing?
