System Information
Kubuntu 16.04

Blender Version
Broken: master, 49c2dbc5db

Short description of error

When there is an animated proxied armature, the armature is of course stored in a library. When reloading that library & saving the main blend file, reopening the main blend file produces an error and the proxy is broken.

Exact steps for others to reproduce the error

Unzip reloading_issue.zip
Open shot_file.blend
In the outliner, right-click "dependent_files/armature.blend" and choose "Reload"
Save the file to shot_file_saved.blend
Re-open shot_file_saved.blend
See the error:

 Pose copy error, pose to:0x7fc5f522c208 from:(nil)
 Proxy copy error, lib Object: Armature proxy Object: group_rig_proxy

Any idea how to avoid this or work around it? Running into this problem repeatedly in various productions, losing lots of animation work.

For anyone googling this, here's my current workaround:

When you open the scene and notice the animation is gone, it's kind of not. What's actually missing is the proxy, the animation data (the action) is still there, but probably only so long as you don't save the file again and reopen it.

So create another proxy from the same rig, and then link the old animation data to it using python:

# With the new proxy object as the active (last selected) object:
bpy.context.object.animation_data_create()
bpy.context.object.animation_data = bpy.data.actions["Whatever the name of the action for the old proxy was, probably the name of the armature and '_proxy' in it"]

That's worked for me so far.
