We should, too.  Possible caching issue with the cache?  Are we caching the cache?  Hehe.

I was going to step through this, but it looks like the tests aren't quite cloning the merge repository correctly?

```
            string path = CloneMergeTestRepo();
            using (var repo = new Repository(path))
```

is failing for me because it can't open the `path` (it's not fully qualified for me).  Travis is having the same issue, it looks like.
