System Information
Operating system: Windows-10-10.0.17763 64 Bits
Graphics card: GeForce GTX 980/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 417.35

Blender Version
Broken: version: 2.81 (sub 15), branch: master, commit date: 2019-10-22 15:34, hash: ac18c3c28d
Worked: (optional)

Short description of error
When reloading a file containing a library override for a collection and when this collection is the "active" collection, any attempt to add a mesh to this colletion causes a crash.

Exact steps for others to reproduce the error
1- open blender
2- link collection "CollectionCube" from "overrideLib.blend"
overrideLib.blend
3- create an override for armature "ArmatureCube"
4- click on the collection "CollectionCube" (make it the active collection)

5- save the file
6- reopen the saved file
7- try to add a mesh (i.e. plane) => crash

Note: does not crash is file is not saved/reloaded (steps 5&6)

Crashes at:
blender.exe!BKE_view_layer_base_select_and_set_active(ViewLayer * view_layer, Base * selbase) Ligne 356 C
blender.exe!BKE_object_add(Main * bmain, Scene * UNUSED_scene, ViewLayer * view_layer, int type, const unsigned char * name) Ligne 887 C
blender.exe!ED_object_add_type(bContext * C, int type, const unsigned char * name, const float * loc, const float * rot, bool enter_editmode, unsigned short local_view_bits) Ligne 480 C

due to NULL selbase passed to BKE_view_layer_base_select_and_set_active()

Sorry, looks like a duplicate of #71030 (I didn't find it when I started to document the repro steps).
Looks also to be the explanation for #70949 (closed, Invalid)
