[DRE-maint] Bug#820505: wiki fails to create

[TheSin]

I’m going to assume this is the issue.

  # Returns the Gollum::Wiki object.
  def wiki
    @wiki ||= begin
      Gollum::Wiki.new(path_to_repo)
    rescue Gollum::NoSuchPathError
      create_repo!
    end
  end

the dir in this call needs to be a git repo according to https://github.com/gollum/gollum-lib

# Create a new Gollum::Wiki object by initializing it with the path to the
# Git repository.
wiki = Gollum::Wiki.new("my-gollum-repo.git")
# => <Gollum::Wiki>

So I think the dir should be made into a git repo, then use Gollum::Wiki.new on it.  I’m not super versed in ruby so I’m still researching how to do this, but it’s my current guess.
