Intermittent crashing when saving a scene

CMacks

Since updating to DS 4.15.0.2, I've noticed intermittent crashing of DS when saving a scene.  Intermittent, meaning sometimes, like 10-15% of the time.  Each time, the scene does appear to save correctly, so that's a relief.  I'm on MAC OS 10.14 and have submitted a ticket.  Anyone else noticing this?  Anyway to avoid it?
