(2679) Bug Report: Crash on "Open" "Parked"

version 3.1.1 b2679
System: Road Hog (stock, no wings, one DMX, USB memory stick)

Twice now, the system has crashed to a blue Road Hog screen when I have pressed "open" "parked" The first time was right after I created a new non-dimmable by changing the type of a desk channel; the second while I was writing cues. Nothing in the logs directory.

I'm uploading the show.
