Short description of error
Crash when overwritting armature pose on Copy/Paste pose with same pose.
Also cache problems are affecting pose gestures and arent being saved on pose library.
Exact steps for others to reproduce the error
On an armature on Pose Mode copy/paste a default pose in the same model and it would crash.
Saving a random pose on the armature, getting to default pose and loading the pose from the saved pose will result on nothing and a empty cache message.
