I downloaded the source for survival and I think I found the bug.  I 
have not tried to build the package with this change to test it, but 
just defining the function with this change seems to work.

The code

	if (conf.int=='only') {
	    conf.int <- TRUE
	    plot.surv<- TRUE
	    }

Should be

	if (conf.int=='only') {
	    conf.int <- TRUE
	    plot.surv<- FALSE
	    }
