Given a armature that was linked from a file, a proxy is created of said armature.
Assigning a linked poselib to this proxy does not facilitate the application of poses in that poslib because the poses are greyed in the UI.
I have attached the relevant files.
Please see tester_consumer for the file that links from tester. tester.blend (618 KB)
