Unreal Engine Issues and Bug Tracker (UE-43887)

Description

Was reviewing test cases for new Bloom feature and was looking at different actors that make use of PP. Happened to select a Camera Actor and Cinematic Camera actor at the same time which led to this crash.

The crash only reproduces when details panel is visible.

Steps to Reproduce

Add a Camera Actor from Place Mode into the level
Add a Cine Camera Actor from Place Mode into the level
Select both Camera Actors

Result: Editor crashes almost instantly
