Issue on gitlab.com: undefined method `scan' for nil:NilClass (NoMethodError)

I'm not sure the right place to post this to? I'm having an issue when I push up to gitlab.com. Is theres some offical gitlab.com support tracker? This one looks more like it's for the FOSS project rather than the SaaS service.
