That's odd. getcwd returning an empty string.
I can only see that happening if you do the equivalent of
chdir("/");
chroot("/somewhere");
getcwd(buf,sizeof(buf));

That would return an empty string with the new code but not with the
old.
But I cannot imagine gnome-vfs-daemon doing a chroot, as it does not
run as root.

You could try removing the
if (*buffer == '/') {
buffer++;
buflen++;
}
from the new __d_path. But that still wouldn't really explain what
was happening.
Maybe also put a WARN_ON(! *buffer) just before the return to find out
exactly what is going on when the empty string is returned.
