### Please describe the problem.
`uuid.log` can end up in a state where `git annex describe` (and probably other things) stops working.
### What steps will reproduce the problem?
Run `git annex describe` against a remote that is not a an initialized git-annex repo.
### What version of git-annex are you using? On what operating system?
debian-packaged git-annex 4.20131106 on Linux Mint 13/Maya (Ubuntu Precise/12.04)
### Please provide any additional information below.
I will follow comments, but can also be found at [[https://microca.st/clacke]].
Full transcript to reproduce:
[[!format sh """
$ git init a
Initialized empty Git repository in /tmp/annex/a/.git/

$ cd a/
$ git annex init

(Recording state in git...)
$ git remote add -f b ../b
