### Please describe the problem.

It seems i have a somewhat corrupted git repository here, not sure how it happened. I was expecting the magic git annex fsck to recover from this, especially since this is a secondary repository and all objects should be available on the remotes...

### What steps will reproduce the problem?

I am really not sure, but i ended up with empty objects in my git repo.

### What version of git-annex are you using? On what operating system?

git-annex version: 5.20141125

### Please provide any additional information below.
