Short description of error
Errors in console when creating proxies.

Exact steps for others to reproduce the error
Unzip group.zip

Open main.blend, select instanced group and create a proxy (Clt+Alt+P). I get:

add_relation(Proxy) - Could not find op_from (ComponentKey(OBEmpty_proxy, 11, ''))
add_relation(Proxy) - Could not find op_to (ComponentKey(OBTorus, 11, ''))

Note: Proxies were not working before fc10484f7c, but this error is prior to that. If you want to test it revert that commit and apply P543 to prevent your Blender crashing.

I have no idea if this problem is depsgraph related or ID refactor related. So although I assigned it to @Sergey it may be related to @mont29 too.

Proxies on non-armature objects were always flackey and were never supported in the new dependency graph. Instead of wasting time now trying to solve this issue would rather either disable proxies on non-armatures or at least wait for static overrides to arrive first. Otherwise it will be fixing same issue twice: first within a broken design and then within a proper design.

This is a known issue, and i do not see why we waste time fixing it right now.

Ah right. It was one of my tests files for my work on collection and groups, ... so I didn't realize the issue was that. That said armature proxies are broken until I force depsgraph refresh (e.g., save and re-open the file, or add a new object). But it's a separated issue since there is no error printing in this case. It was even more broken before fc10484f7c - not even saving/reopening fixes it back then.

Try this first in bpy console:

C.scene.depsgraph.debug_rebuild()

if that solves the issue, it means you're lacking DEG_relations_tag_update() after all proxies were created.

Note to self: I'm tagging the scene before adding the object to the collections. I may need to split the object_add_common in a pre and post routines. (I'll try tomorrow).

Shouldn't matter if you tag before or after. Just make sure relations are tagged for update before exiting operator.
