I didn't know the list of objects I'm missing, but I used this little script do find them:

anchor=7cb192eab0251911e2ca77d4ecceb621dd2d34f5
while true
do
    outp=$(git log --pretty=raw --raw $anchor 2>&1 >/dev/null)
    echo $outp
    [ $#outp -eq 0 ] && break
    cmt=${${outp##* \(}%\)}
    git cat-file -t $cmt >/dev/null 2>&1 && \
      cmt=$(git cat-file commit $cmt |grep '^tree ')
    echo ${cmt##* } | ssh server cd git\; git pack-objects --stdout | \
      git index-pack --stdin >/dev/null
done

Maybe it helps someone else. :)

But now, there's something else broken.

Can someone tell me what I'm doing wrong?

fsck --full reports only dangling objects, no breakage.
