Rails, which GitLab is based on, uses suffixes to select content renderer (such as .html, .json - apparently in case sensitive manner), also I think it will serve underlying files in some cases (e.g. the example of dashboard.html) given elsewhere. The proper fix is to disable this mechanism at least for the username segment of gitlab path but perhaps GitLab developers are too lazy or unaware or just in rush.
