GitLab

I have just set up a new repository and, because I want to use issues as a kind of task tracker, I've gone into the issues to add some todo-like stuff. Upon clicking 'add new issue' I get a 500 error. I have other repositories with commits and adding issues is not a problem, but it is in this blank repository. The relevant lines from the production log file are:

Presumably, Gitlab assumes that your repository will have some files/commits when getting repository.contribution_guide.

I can try to provide more details on request, though this probably points you in the right direction.
