UE4 closes when clicking on object while in Matinee

Hello. Matinee (and all of UE4 with it) seems to crash at intermittent times when clicking on certain actors in the world.

I’m having the same problem as outlined here: https://answers.unrealengine.com/questions/254438/matinee-crash-without-crash-report.html

Strangely, that post was almost 6 months ago and the problem is still persisting. Any idea when this will be fixed?

P.S. If you want to know what my log looks like, just look at his. It’s virtually the same thing, including [2015.07.08-03.53.33:854][858]LogEditorViewport: Clicking on Actor (LMB): StaticMeshActor (Floor) as one of the last things I see on the log report.
