Currently my git repo layout is as follow
$ pwd
<local master copy>/qgit.git/.git
$ ls
branches/  description  HEAD    index  objects/   refs/
config     FETCH_HEAD   hooks/  info/  ORIG_HEAD  remotes/
$ ls objects
2c/  32/  53/  5c/  6a/  info/  pack/

The host copy should be the exact mirror of the local copy (I use
sitecopy to sync
host). I have also verified this directly accessing the host with ftp.

So the 8d/ea0351... file is really not existent. BTW I have run git
prune and git-prune-packed
also.

Finally accessing the missing object with a browser

http://digilander.libero.it/mcostalba/
scm/qgit.git/objects/8d/ea03519e75f47da91108330dde3043defddd60

gives a pre-canned (in italian) 'Sorry page not found' stuff.

So I really think the site "HTTP/1.0 200 OK" response it's a fake.
Perhaps security related to avoid sniffing (just a guess because I have
absolutely zero competence in security related things).
