Looking at the fetch function in gitcore.py -

http://code.google.com/p/django-rcsfield/source/browse/trunk/rcsfield/backends/gitcore.py#45

def fetch(self, key, rev):
    """
    fetch revision ``rev`` of entity identified by ``key``.

    """
    repo = Repo(self.repo_path)
    try:
        return repo.tree/key.data
    except:
        ...

Rev is not used ... and this will hit the except clause everytime returning '' ...

Here is a quick hack fix:

def fetch(self, key, rev):
    """
    fetch revision ``rev`` of entity identified by ``key``.

    """
    repo = Repo(self.repo_path)
    try:
        bits = key.split('/')
        tree = repo.tree(rev)
        for bit in bits:
            tree = tree/bit
        else:
            return tree.data
    except:
        return ''
