Windows 7, R-2.11.1 and R-2.12.0beta

When I do

file.info(list.files(getwd()))

I get what I expect, a dataframe with a lot of variables,
especially isdir, which tells me if the named object
is a file or a directory.

In the result of

file.info(list.files(paste(R.home(),"library",sep="/")))

all variables have only NA values, even when I start R
in elevated mode.
