It appears that the actor isn't properly destroyed until the exit, despite being deleted. By that time, the root component (the brush) has already been destroyed, thus when it's accessed in AAudioVolume::PostUnregisterAllComponents(), the crash occurs.
Place an AudioVolume in a level.
Save the level
Make a new level
Reopen the level with the volume
Delete the volume
Save the level
Make a new level
This is where we experience the crash.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-36553 in the post.
