Short description of error
For this armature the action editor is broken (I can clone actions but can't create, push down, stash etc).
It seems as though it's behaving the same way as if I had nothing selected.
Every time I select an action in the action editor, it's number of users count increases by 1. This does not happen on non broken objects.
Clue: In the NLA editor, it seems as if the Armature is in tweak mode, but I can't get out of tweak mode.
Exact steps for others to reproduce the error
Open that blend file. Select the armature.
In the Action Editor, notice that the controls for create action, push down and stash are greyed out.
Select a different action in the action editor, select the previous action. Notice how the reference count increases.
