AimOffset and Blenspace graphs causing crash for some users

Users are experiencing crashes when using the AimOffset and Blendspace graphs. I am unable to reproduce this locally, but judging by the Bugg in crash reporter, this is not an isolated incident.

• I reimported some new animations and played with the blendspace values. While hovering with the mouse over the blendspace graph the application freezed. I noticed in the taskmanager a steady increase of the ram usage starting by ~ 1.4 GB. After reswitching to the editor it shut himself down.
• Hi!
  I make "Creating Blend Spaces" from
  https://docs.unrealengine.com/latest/INT/Gameplay/HowTo/CharacterMovement/Blueprints/BlendSpace/index.html
• was looking at anim blueprint. Nothing special. Unedited demo project!
• Crashed whilst dragging node around within AimOffset graph editor.
• I was working on an animation blend space and about to drag an animation.
• Was hovering with the mouse over the blending preview in the Blend Space viewport. This is the second time this has happened.
• Visualizing the aim offset blend space for "Owen" from the content exemple demo

1. Open ContentExamples
2. Find Owen_AimOffset in the Content Browser
3. Open it
4. Drag your mouse around the AimOffset graph
5. Particularly try the bottom left corner

Result: For some users, the bottom left corner causes the crash. Others simply move the mouse around or let it hover over the graph.

1. Open ContentExamples
2. Find Owen_Locomotion_Blendspace
3. Open it
4. Drag your mouse around the blendspace graph

Result: Crash while moving the mouse around
