zlib inflate problem

Big problem for me :

paul at kubuntu: gpg bigfile.pgp
gpg: fatal: zlib inflate problem: invalid block type
secmem usage: 1920/3872 bytes

I've seen this problem mentioned several times on the lists but never seen a 
working solution. I have 28GB of data sitting in GPG encrypted archives (4GB 
each). I can't some of the archives and I can't get hold of the original data 
I'm running gpg (GnuPG) 1.4.1 with zlib 1.2.3 on a Kubuntu Breezy system.
The system that encrypted the data was running gpg (GnuPG) 1.4.1 with zlib 
1.2.2 on Debian Sarge.

My questions are :
1. Was the bug on the encrypting side or decrypting side?
2. Is there any way to recover the data I have sitting in the archives or did 
gpg/zlib screw up my data good and proper? Must I kiss the data goodbye?

One slightly pissed off first time user who would like to get his data back.
