I think it's worth noting that on Blender 2.82a it doesn't crash but it logs the following:

@Erick Tukuniata (erickblender) (cc @Alaska (Alaska)) this file is too complex (52MB). It is up to the reporter (or the community) to simplify it before it can be considered confirmed.

Normally .blend files can be simplified by removing most objects and disabling settings, until the problem reveals itself more clearly. The file should be as small as possible.

This is a .blend file from Blendercloud, did you ask the Blendercloud people to confirm the crash? Can they simplify the file? This report is me indirectly pointing a problem that they have in the Blendercloud.

I didn't know this file was from the blendercloud.

Still, it would have helped if someone could simplify it, but I will do it myself.

This is trivial fix, just missing check for NULL rna path in driver (which is done everywhere else in code)... Fix incoming.
