System Information
Ubuntu 18.04, 64 bit, Intel 6700 CPU, Nvidia 1060 graphics.

Blender Version
Broken: 2.80-2e10c658f42
Working: 2.79

Short description of error
On loading this file, Blender consistently segfaults on my system. Sorry it's a bit big (~22MB), deleting stuff seemed to make the crash go away.
