Good point. And it actually accidentally solved my problem.

Previously I attached .Rdata files. After your email I exported this 
dataset into a csv file and then re-loaded it to see if the problem 
persists, and... the problem disappeared.

Nevertheless, if I load the original .Rdata file, the problem is back 
again. This makes no sense to me - there must be a bug in R, or in the 
survival package.
