Problem cloning over ssh with git submodule and tags

Hello,

I have a problem with submodule in v1.6.3.3:

The following sequence gives me error messages and I can't clone a
repository over ssh (for details see the attached typescript):

git submodule add git://git.kernel.org/pub/scm/git/git.git git
cd git
git checkout v1.6.3.3
cd ..
git add git # because it's modified
git commit -m 'added submodule git @ tag v1.6.3.3'

cd ..

git clone dornberg@dong101:tmp/test sshclonetest
error: git-upload-pack: git-pack-objects died with error.
fatal: git-upload-pack: aborting due to possible repository corruption on the remote side.
remote: Generating pack...
remote: Done counting 7 objects.
remote: error: unable to find cff4231a1dfbe68b4a163b31406d862567d3243a
remote: fatal: unable to get type of object cff4231a1dfbe68b4a163b31406d862567d3243a
remote: aborting due to possible repository corruption on the remote side.
fatal: early EOF
fatal: index-pack failed

 # cff423... is the v1.6.3.3 tag in the git submodule

git clone test localclonetest
 # this works though

If I change the URL in localclonetest/.git/config to
ssh://dornberg@dong101/path/to/testrepo I can do normal pulls from the
repo. (Haven't tried to change the git submodule to another tag or
something else yet, though.)

Let me know if I shall try out something. (I'm not subscribed to the
mailing list.)

Greetings,
 Mike Dornberger
