Unreal Engine Issues and Bug Tracker (UE-21916)

Description

Using the HideCategories = (CameraSettings) specifier inside a custom CameraComponent class will cause the editor to crash when the component is added to a blueprint. Restarting the editor will show that the component was added to the blueprint however selecting the component will crash again.

Steps to Reproduce

Open UE4 Editor (any project)
Add class based on CameraComponent (MyCameraComponent)

In MyCameraComponent.h add the following to the UCLASS() macro:

BlueprintType, HideCategories=(CameraSettings), ClassGroup = (Custom), meta= (BlueprintSpawnableComponent)

Compile
Create a new blueprint based on actor (ActorBP)
Add My Camera component to ActorBP

Result:
Editor immediately crashes after selecting the custom camera component
