[[!meta title="git annex uninit causes SqlLite3 error"]]

### Please describe the problem.
I am basically having issues with `git annex uninit`

### What steps will reproduce the problem?
    $ git init localrepo
    Initialized empty Git repository in /Users/w/work/temp/test/localrepo/.git/
    $ cd localrepo
    $ git annex init
    init  ok
    (recording state in git...)
    $ git annex uninit
    fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
    Use '--' to separate paths from revisions, like this:
    'git <command> [<revision>...] -- [<file>...]'
    Deleted branch git-annex (was 98f3795).
*********************
Now if I add a local file I get a different error

    $ git init localrepo
    Initialized empty Git repository in /Users/w/work/temp/test/localrepo/.git/
    $ cd localrepo
    $ git annex init
    init  ok
    (recording state in git...)
    $ date > secret_file
    $ git annex add secret_file
    add secret_file ok
    (recording state in git...)
    $ git commit -am "added"
    [master (root-commit) a2e1882] added
     1 file changed, 1 insertion(+)
     create mode 120000 secret_file
    $ git annex sync
    commit  
    On branch master
    nothing to commit, working directory clean
    ok
    $ git annex uninit
    unannex secret_file ok
    Deleted branch git-annex (was 6a727da).

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

I am super excited about what I can do with git-annex. I hope to setup and maintain encrypted repo(s) of some of my files, and access them by cloning a local copy of the encrypted repo and getting the files I want, using them, and then deleting the local copy.
