Intermittent data corruption in gpg 1.2.0

Any help would be appreciated.
Most of the time, it works perfectly. But for some files, it fails about
10% to 20% of the time. One such file is /var/lib/dpkg/available, which is
a
debian file.
When I decrypt, gpg complains:
gpg: [don't know]: invalid packet (ctb=14)
I tried several ways to recreate it without using gpg, but it never
happened without it, which is why I am posting here. I'm not 100% certain
it's gpg that's causing the corruption, however, because it's hard
to recreate without calling gpg from afio.
A typical input that sometimes causes data corruption:
$ find /var/lib/dpkg/available /var/lib/dpkg/available |
afio -oz -Z -U \
-P gpg \
-Q --batch \
-Q --no-options \
-Q --homedir -Q $homedir \
-Q --always-trust \
-Q --no-auto-check-trustdb \
-Q --recipient -Q "${qid:?}" \
-Q --debug-all -Q -vv \
-Q -e \
-3 0 \
"$qofile"
Typical output:
(The real output is huge, but to spare everybody's mailboxes I elided it
with "...".)

Can anybody help? I don't know what else to do. I am using debian sarge,
