Possible git status problem at case insensitive file system

All:
        I use msysgit 1.7.0.2 at windows xp.
        Problem: git status will list tracked directory as untracked dir.

        5. git add a.c
        6. git commit -a -m "test"
        7. cd ..
        8.  mv d d1
        9.  mv d1 D
       10. git status

# On branch master # Untracked files: # (use "git add <file>..." to include in what will be committed) # # D/ nothing added to commit but untracked files present (use "git add" to track)

        D/ should be same as d/ at case insensitive file system.
        D/ should not listed by git status.
