Student filter breaking Debian installs

[Berni Elbourn <berni@elbournb.fsnet.co.uk>]

Hi,

Our nice network chappie has opened restriction on .gpg, .gz .bz2  .deb 
and files without . but something is is still not working...

Here's a log of an aptitude update:

94% [6 Translation-en_GB bzip2 0] [Connecting to ftp.uk.debian.org 
(83.142.228.bzip2: (stdin) is not a bzip2 file.
Ign http://ftp.uk.debian.org lenny/main Translation-en_GB 

63% [7 Translation-en_GB bzip2 0] [Connecting to ftp.uk.debian.org 
(83.142.228.bzip2: (stdin) is not a bzip2 file.

And then things fall apart...repeating gets forever.

I am sorry but looking over the repository I cant find Translation-en_GB

What real file is involved here please so we can add to the filter 
exceptions?

Are there any others we should check?

ta
