It is not critical but in case of coxph.null model (~1)
extractAIC function generates
       Warning message:
        In is.na(fit$coefficients) :
        is.na() applied to non-(list or vector) of type 'NULL'
As I understand it happens because of absent coefficients attribute.
Function stats:::extractAIC.coxph
Line edf <- sum(!is.na(fit$coefficients))

I think extra null-checking would be useful here.
