Well, one could argue that this is a bug in your package.

Here is what I do on our CRAN mirror, inside the
  bin/windows/base  directory :

$ md5sum R-3.2.0-win.exe
c3f8654826ce772d0105373b85804b0d  R-3.2.0-win.exe
$ cat md5sum.txt
c3f8654826ce772d0105373b85804b0d *R-3.2.0-win.exe

and so I conclude that the MD5 sum is correct.
In case of doubt, I rather trust a human than an algorithm, but
it seems that I'm slowly becoming part of a minority .. ;-( ;-)

So the bug might be that your package code gets upset by the "*"
before the R  ?
.... and that may also be the glitch on the CRAN maintainer side..

I know that you know better, Tal ;-)
