GPG corruption

This is with [root at csebeo v]# gpg --version
gpg (GnuPG) 1.2.1

I put 12 files into a .tar:
tar cvzf b.tar bp*

I encrypted them with a symmetric key:
gpg -c b.tar

The result was fairly large (this is running on an opteron running
redhat RHEL):
ls -alh b.tar.gpg
-rw-r--r--    1 root     root         4.1G Feb  1 23:25 b.tar.gpg

Now to decode it:
gpg --output b.tar --decrypt b.tar.gpg
gpg: CAST5 encrypted data
gpg: [don't know]: invalid packet (ctb=75)
gpg: uncompressing failed: unknown compress algorithm

The resulting file is partially there:
$ ls -alh b.tar
-rw-r--r--    1 root     root         103M Feb 10 14:16 b.tar

Tar seems to think it's valid:
tar tvf bg-s01-s12.tar
drwxrwxr-x root/root        0 2005-01-28 17:51:28 bpdata/
-rw-r--r-- root/root 36955832 2005-01-16 17:47:40 bpdata/bd.001

Any ideas?
