Short description of error
When I try to apply dyntopo on the mesh extracted from mask Blender crashed.

Exact steps for others to reproduce the error
Draw mask on mesh, extract it, try to use dyntopo or the new remesh.

Event Timeline

The extracted mesh crashes in those situations:

When removing the Solidify modifier and entering Sculpt Mode.
When trying to use Dyntopo.
When trying to put a mask on it.
Even when applying the Solidify modifier and entering Sculpt Mode.

It crashes when I copy it to 2.80 also, so it's probably something wrong with the originated mesh.

Germano Cavalcante (mano-wii) lowered the priority of this task from 90 to High.

While trying to reproduce the crash, I came across an assert on this line:$1788

It's probably related.
