cloning with subrepos to an ssh url

[Julius Ziegler]

Hello,

I am having problems cloning a repository containing subrepos to an ssh 
url. At first I thought my problem is related to this
http://selenic.com/pipermail/mercurial/2010-September/034737.html , but 
now I think that its more basic. Here is an example:

# setup simple example repo with subrepo
hg init dog
cd dog
hg init cat
echo cat=cat > .hgsub
hg add .hgsub
cd cat
echo meow > meow
hg add meow
cd ..
hg commit -m"added somthing"

# try to clone this to my_server, via ssh
cd ..
hg -v clone dog ssh://my_server/repos/dog

running ssh my_server "hg init repos/dog"
running ssh my_server "hg -R repos/dog serve --stdio"
searching for changes
1 changesets found
remote: adding changesets
remote: adding manifests
remote: adding file changes
remote: added 1 changesets with 2 changes to 2 files

If I now ssh to my_server, the directory repos/dog is there,
but it has no working copy:

find repos/dog

repos/dog/
repos/dog/.hg
repos/dog/.hg/branchheads.cache
repos/dog/.hg/00changelog.i
repos/dog/.hg/undo.desc
repos/dog/.hg/undo.dirstate
repos/dog/.hg/store
repos/dog/.hg/store/undo
repos/dog/.hg/store/data
repos/dog/.hg/store/data/.hgsubstate.i
repos/dog/.hg/store/data/.hgsub.i
repos/dog/.hg/store/fncache
repos/dog/.hg/store/00changelog.i
repos/dog/.hg/store/00manifest.i
repos/dog/.hg/undo.branch
repos/dog/.hg/requires

Having no working copy is actually the first thing that puzzles me, but 
this also happens if I do not have any suprepos. In that case, however, 
I can restore the working copy by hg update. But in the case with a 
subrepo, this gives me:

cd repos/dog
hg up

pulling subrepo cat from /home/ziegler/repos/dog/cat
no changes found
abort: unknown revision '14aad4f7de9a6a86b282b5de60279e154da63079'!

I am really clueless! Why is this not working?

Thanks!

Julius
