"ErrorException Undefined index: contributors" on route /repository/{name}

[pauly4it]

I've set up git-pretty-stats on a per-project installation of homestead. The home view works fine, showing the two repos I've cloned into the repositories directory.

When I click on one of the repositories, I see the loading bar at the top of the page and then nothing happens. The console shows a 500 being returned from repository/repo_name. So I browsed to repository/repo_name and got "ErrorException Undefined index: contributors".

Here's the stack trace from the logs:

Any ideas on what's going wrong?
