We are using hierarchical project organization heavily, but some of our parent "project" just implement departments under which real projects with planned version are configured. In the departments parent projects we activated issue module and hoped to see the Versions of all sub projects in its roadmap.
But this only works if at least one version is configured in deparment (parent) project. If not the Roadmap tab isn't even displayed!
This behaviour is very wired and doesn't make sense for. Either in every case version are showed in the roadmap (for all childs too) or not, but not only if parent also has version defined.

Thats why we think it is a bug.
