First think ... try this

sfit <- summary(fit, rmean = "individual")
sfit$table[5]

Hmmm. Second think. I suppose it's also possible that some of my  
unsuccessful efforts last evening are having durable effects. In  
particular, after reading the code, I tried at one point setting two  
options:

options(survfit.rmean = "individual")
options(survfit.print.rmean = "individual")

I hate writing this but since I don't know the causes for our  
different results ... Good luck.
