-In our family repository, we had an event where git-annex committed a bad
-merge commit. This had the effect of seeming to delete all the files
-in the repository. However, it is completely recoverable with no file loss.
-
-Other users have reported apparently the same problem.

-> This appears to be a race, and I have put in a fix for that.
-> It will be released in git-annex 5.20140709.

-> It's a little bit difficult to say for sure that the bug is fixed, since
-> I don't have a good way to reproduce it. However, everything I am seeing

-## recovery
-
-Look through the git log for the bad commit. It will be the one 
-that deletes a lot of files. Since the bad commit is a merge commit,
-you need to include the -c switch:
-
-	git log -c --stat
-
-Once the bad commit sha is found, revert it. Since it's a merge commit,
-you will need to pass -m 1 to git revert. If the repository you're working
-is uses direct mode, you will first need to switch it to indirect mode.
-
-	git annex indirect
-	git revert -m 1 a36077cf1234eeb755fec8f699d3cbaaee817bac
-
-(It's possible, but I think unlikely that this will pick the wrong
-branch of the merge to revert. If it did, "git reset --hard HEAD@{1}" and
-redo, passing `-m 2` instead.)
-
-Once the revert is done, all your files should be back. You can switch
-the repository back to direct mode if desired (`git annex direct`)
-and can `git annex sync` to push the fix out to all other clones.
-Everywhere the fix lands should restore the deleted files. 
-
-Note that it's possible that some repositories may have pruned the deleted
-files as unused. This is most likely to happen in the repository that made
-the bad merge commit in the first place.

-## analysis
-
-In the one case I have of this happening, the commit was made by the
-git-annex assistant, in direct mode. It was git-annex version 5.20140613.
-This version had a bug that caused it to do unncessary merge commits.
-That bug has been fixed in 5.20140707.
-That is apparently related, in that it caused the assistant to do much more
-work than normal. 
-
-But, I don't think that bug is fully responsible for the
-problem. I think a few users have run into this bug before, although I have
-never succeeded in getting a full problem description from anyone who might
-have. I think that the unncessary commit bug made it more likely to happen.
-(This suggests a race may be involved.)
-
-The bad merge commit looked like this:
-
-<pre>
-commit a36077cf1234eeb755fec8f699d3cbaaee817bac
-Merge: 52ecff2 9d8bfd4
-Author: xxx
-Date:   Mon Jul 7 19:58:18 2014 -0400
-
-    merge refs/heads/synced/master
-</pre>
-
-Both parent trees were good and contained all files. In fact, the 2
-parent trees contained the same set of files. But the merge commit
-"resolved" the merge by deleting all the files.
