This is a situation where I wiped out old date
using the me.verts = None first, then started to
reuse the mesh -- maybe when the me.verts is wiped
out the flag that tells the vertex colors that there
are no faces needs reseting?

I'll try to upload a blend when I get a chance
-- the particular blend I am using links to the
VTK libraries so it's probably not a good clear example.
The crash does not happen immediately after extending
the faces, but happens when I start setting col's
of the faces (usually happens after the first couple
of faces, but I have had it work for up to 5000 faces
before it crashed).
