Downloading a zip archive of a repository fails

#Installation info:
Server OS: Ubuntu 14.04.3
Gitlab version: 8.3.0
Web server: Apache 2.4.7

Hello all,

I’m having trouble downloading zip archives of repositories from my Gitlab server. When I’m on the project page and hit the download icon next to the clone URLs, I just get a page with some text on it:

{"RepoPath":"/var/opt/gitlab/git-data/repositories/cgreene/scales-android.git","ArchivePrefix":"scales-android-master-7f6e80ae0fb48e653e89df412dd1f44e1fce5d8f","ArchivePath":"/var/opt/gitlab/gitlab-rails/shared/cache/archive/scales-android.git/scales-android-master-7f6e80ae0fb48e653e89df412dd1f44e1fce5d8f.zip","CommitId":"7f6e80ae0fb48e653e89df412dd1f44e1fce5d8f"}

Any ideas?

Bump. Can anyone help me here?
