Blender seems to crash when adding both a dynamic paint & surface deform
modifier. It works when it is just the surface deform, but should also work along with other modifiers.

Add a UV sphere > Duplicate(don't move) > Add Dynamic Paint & Surface Deform modifier to original Sphere > Set duplicate sphere as target & bind > Blender Crashes..

It seems like me->mvert- [x].co generates a NULL pointer in blenkernel/intern/mesh.c.
Guessing this is depsgraph related...

This is not a dependency graph related, at least not immediatelly related to it. This is an operator.

@mont29, mind having a look? You did some refactor quite recently in the area. Not sure whether something got broken in library/cow-related areas since your fixes there?
