Isn't the error message clear (:->), it is trying to contour the surface,
but it cannot, because there are no scalars defined :). You can view your
file using

$ mayavi2 -d foo.vtk -m Outline -m Surface

I just tried, and it works. But that doesn't solve your main problem,
that is that what you tried first should work.

Damn. This works on my box (ubuntu hardy) both with mayavi2 from branches
and trunk. I suspect a distribution problem. This reference to an
undefined symbol in libxml2 feels like there has been some API
breakage/linking problem with libxml2.

I am not too sure that the problem is in the Mayavi2 or TVTK code base.
