Short description of error
Blender crashes when issuing an undo operation immediately after linking a collection when an Outliner's display mode set to Blender File
It doesn't matter how many Outliners are open, as long as one is set to Blender File.
This only happens when linking, not appending. No other data blocks causes the crash except collections.
Exact steps for others to reproduce the error
Apparently the issue occurs only if the linked collection also has linked stuff? In the test case, the collection to be linked has linked materials.
Blender does not crash when linking standalone collections.
Download these files:
- Open TEST.blend
- Link a collection from 2.blend (2.blend has an object linked from 1.blend; now the Outliner has 2 linked files)
- Undo the operation (Ctrl+Z)
