Git over samba - unable to write sha1 filename | Permission denied

Question

When I am using git over samba share on windows I get an error when i want to commit a file via git_extentions or tortoiseGIT. The error is: error: unable to write sha1 filename .git/objects/b4/e819f886bf31b67c42249a0eff8e8b16cf7622: Permission denied. When I add the file via the ubuntu server and commit the file it works fine. I am also working in a banrch.

I have already tryed chmod 777 the whole .git folder.

I've seen this, too. It's a git defect, likely to do with how it creates and modifies files. To clarify the problem:

# mount a samba share locally. 
$ mount -t cifs options //share/project  /mnt/project

# The share contains a git checkout.
# Do some typical development.
$ cd /mnt/project
$ vi file    ## ok
$ git pull   ## ok
$ git status ## ok
$ git add file ## error!
  error: unable to create temporary sha1 filename 
  .git/objects/8b/tmp_obj_mYE1Xi: Permission denied


## But everything from the shell seems to work.
$ ls -latr .git/objects/8b/  ## ok. empty dir.
$ touch .git/objects/8b/tmp_obj_mYE1Xi ## ok.
$ echo test123> .git/objects/8b/tmp_obj_mYE1Xi ## ok.
$ cat  .git/objects/8b/tmp_obj_mYE1Xi  ## ok.
test123
$ rm  .git/objects/8b/tmp_obj_mYE1Xi  ## ok.

In git version 1.5.6.5 (latest Debian package), you get the error when you try to git-add. If you install git 1.7.3.2 (latest release), you can add the file, but you will get the error when you attempt to commit.
