GitLab

Created by: spotzero

We're having a strange issue with Gitlab 7.3.1

Steps:

1. Created a repo.
2. Pushed master branch. 3, Pushed another branch.

The user who pushed the branches then gets a 500 error on every single gitlab page. Gitlab works normally for other users, expect for the activity feed on that project, which is blank.

Another user pushed a commit to the second branch of the offending project, and now that user also gets 500 errors on every page.

We see the following in the gitlab/log/production.log file:

We've tried clearing the asset cache and restarting gitlab, but the problem persists.
