Short description of error
Create an armature, enter Pose Mode and press Shift+A to open the add menu.
It looks like someone tried disabling all items, but half of them are actually still selectable:
I propose to disable the add menu in Pose Mode, matching all other modes behavior (besides Edit Mode, of course).
