It seems that the latest released version of survival4 (which as far as
I know is not meant to be used with the `final' 0.50 which will in fact
be a 0.60, hopefully soon) has versions of model.frame and
model.frame.default which break things.

For me (note under the current development snapshot, so maybe not under
0.50-a4) it works to do
	rm(model.frame, pos = N)
	rm(model.frame.default, pos = N)
where N is the position of the survival4 package in the search list.
