[BUG] git-gui regression in 2.0rcX within submodule

In 2.0rc2, git-gui is unable to work inside submodules, where 1.9.2 did not show such a problem:

yann@home:~$ cd /tmp/ yann@home:tmp$ mkdir foo yann@home:tmp$ cd foo/ yann@home:foo$ git init Initialized empty Git repository in /tmp/foo/.git/ yann@home:foo (master)$ git submodule add git://git.debian.org/git/collab-maint/tulip.git debian Cloning into 'debian'... remote: Counting objects: 317, done. remote: Compressing objects: 100% (199/199), done. remote: Total 317 (delta 184), reused 166 (delta 95) Receiving objects: 100% (317/317), 73.81 KiB | 0 bytes/s, done.

Initial commit

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)

        new file:   .gitmodules
        new file:   debian

yann@home:foo (master)$ (cd debian/ && git gui) [errors out after showing the following error dialog]

| No working directory ../../../debian:
| 
| couldn't change working directory
| to "../../../debian": no such file or
| directory

strace shows the failing chdir call is from git-gui itself, after getcwd() told him that it is in the dir that is indeed the workdir already.
