If you're still open for suggestions/alternatives, have a look at Phabricator. August-December of 2014 I looked at several different solutions for my company (though primarily my focus was on code review features - today we also use it in some areas for task management and documentation/wiki). I nearly moved forward with GitLab before (re)discovering Phabricator. I like to keep up to date with new features in the alternatives (GitLab, GitBucket, Gogs, Reviewboard, etc.) but at this point I can't imagine wanting to move off Phab.
