It goes a bit further than that. After debugging the error, I found out that, when setting the physics' type to keyed, and proceeding to trigger the crash, the object's particle system somehow loses it's psys->particles reference, which in turn makes it return a psys->totpart of 0, which makes the object become an "invalid target", which makes the gpu_batch module thingie crash because verts is 0. I've been trying to find out why the particle reference is clearing its psys->particles.
Maybe there's something that's missing, something i don't understand about blender's pipeline.

it doesn't happen either if you have more than 1 particle system in the object

This didn't happen in blender 2.79b, and as far as i've been able to dig, it's an issue with the gpu_batch module. Maybe someone with experience in that area could chime in?

Using the provided blend files i can assess that:
