Lenny, aptitude and md5som problems

[Magnus Pedersen <bofhenator@gmail.com>]

I've been getting the following error when i try to:
aptitude upgrade

E: Failed to fetch 
http://ftp.dk.debian.org/debian/pool/main/g/glibc/locales_2.5-9_all.deb: 
MD5Sum mismatch

I get the same eroor with doc-linux-text. These errors are blocking any 
other upgrades, am I the only one seeing this?
