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