[BUG] Submodules problem with subdirectories and pushing

[Frank Lichtenheld <frank@lichtenheld.de>]

Hi.

I have a git repository where I include several submodules. This seemed to
work fine until the server I push to got (finally) updated from 1.5.something
to 1.6.4. Now I get an error if I try to push.

The issue is easily reproducible with a minimal repository for me:

Creating an empty repository on server:

flichtenheld@git-test:~$ git version
git version 1.6.4    <---- Directly compiled from git
flichtenheld@git-test:~$ mkdir test.git
flichtenheld@git-test:~$ cd test.git/
flichtenheld@git-test:~/test.git$ git init --bare
Initialized empty Git repository in /home/flichtenheld/test.git/

Creating repository on client:

frl@dhcp-rnd-054:~/tmp$ git version
git version 1.6.3.3   <--- From Debian Package
frl@dhcp-rnd-054:~/tmp$ mkdir test
frl@dhcp-rnd-054:~/tmp$ cd test/
frl@dhcp-rnd-054:~/tmp/test$ git init
Initialized empty Git repository in /home/frl/tmp/test/.git/

Add a random submodule:

frl@dhcp-rnd-054:~/tmp/test$ git submodule add git://repo.or.cz/git-browser.git subdir/git-browser
Initialized empty Git repository in /home/frl/tmp/test/subdir/git-browser/.git/

git-browser

All seems to work fine if I add the submodule as git-browser instead of as subdir/git-browser.

Gruesse,
