Wrong md5sum for python-twisted

[alberto <listas@toscat.com>]

Hi list,

I'm trying to install python-twisted from 
http://ftp.nl.debian.org/debian-amd64/debian but apt-get fails with a:
Failed to fetch 
http://ftp.nl.debian.org/debian-amd64/debian/pool/main/t/twisted/python-twisted_1.3.0-8_all.deb 
 MD5Sum mismatch

Thanks!
Alberto
