I construct a mesh using Triangle and convert it using dolfin-convert to generate the mesh.xml file. After importing dolfin, I load the mesh. But calling SpatialCoordinate on the mesh raises an error.

mesh = Mesh("mesh.xml")
x = SpatialCoordinate(mesh)​

Raises:

UFLException: Invalid cell <Mesh of topological dimension 2 (triangles) with 2507 vertices and 4847 cells, ordered>​

How can I use SpatialCoordiate without getting this error?

Are you sure the problem is not in your mesh? I tried with a UnitSquareMesh and have no problem.

I can solve problems on this mesh and plot the solution with no difficulty. What kind of problems in the mesh might lead to this behaviour?

You can try to upload the mesh if this is not too big!
