All tabs to manage the current content (Preview / Details / Translations / Locations / Relations / Roles / Policies) don't work in the user section.

For example, on a brand new 2013.4, I can't manage translations, or locations... on the "users" object [User group] on the url : /content/view/full/5

Tested on two differents environments, with and without admin2.
No problems for content and media sections.
