Hi, I've been playing around with dolfin for a week or so now and love 
it, but have been having problems with some pydolfin demos.

Here is the error I get:

---------------
Reading mesh from file tetmesh-4.xml.gz.
*** Error: Missing attribute "celltype" for <mesh> in XML file. 
[XMLObject.cpp:125: parseString()]
----------------

This particular error occurs when i run elasticitysolver.py in the 
/src/demo/scripting/pydolfin/solvers/elasticity directory. I receive 
nearly identical errors when trying out any other demo featuring 
tetmesh-4.xml.gz,

cow05b.xml.gz and cow05c.xml.gz when running test.sh in 
/src/demo/scripting/pydolfin,

and possibly some others I'm forgetting.

***Note, tetmesh-4.xml.gz seems to work in the directory 
/src/demo/scripting/pydolfin/solvers/elasticity-tpde/manual *** I COULD 
just copy it over, but that's not the point :-)

Unrelated, here are some other errors I'm getting:

I am running a freshly downloaded hg cloned (as of this morning, 
29/11/2006) compiled with PETSc 2.3.1 enabled.

Thanks and keep up the good work!
