Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Broken: version: 2.83.0, branch: master, commit date: 2020-06-03 14:38, hash:
211b6c29f7Worked: (newest version of Blender that worked as expected)
Short description of error
Dragging and dropping a Collection with a Collection Instance inside it, into another Collection is causing Blender to crash.
Exact steps for others to reproduce the error
Drag and drop the "Views" Collection inside the "Suzanne" Collection.

Changed status from 'Needs Triage' to: 'Confirmed'
Can confirm, checking...

same as #77595
Caused by
ed386507e1.Not sure this is really a duplicate of #77557 (Python Operators that add/remove ID data without an undo step crash Blender) (which #77595 was closed as a duplicate of)?
And
eaff606f2dshould have fixed {#77460}?In any case, I am leaving this open for now because I think parenting should just not be allowed in this case, will check if doing this in the poll is too expensive.
Will claim for now, check tomorrow.

This as been fixed by
eaff606f2d, which checks and forbids such recursion in collections.Closed as duplicate of #77460
Uff, terribly sorry, seems like I was a couple of commits behind, sorry for the noise!
