I just tried it in an "emacs -Q" window. Did a dired of my Users home directory and there did an R of an existing file to "newname".  The line containing the file disappeared.

In other words: "emacs -Q" made no difference: the problem remains.

As I stated before, I did not observe this problem on an IBM Thinkpad 
running Windows XP Pro SP3.
Now I'm using a Toshiba Satellite P740 running Windows 7 Home Premium SP1
    

I tried on Windows 7, and didn't see the problem.

  
The problem has shown up on every rename in a dired buffer on this machine.
    

Strange, it doesn't happen for me.  Do you see that in "emacs -Q"?
