SUPERLU Type and MatMatSolve()

Just wondering if it is possible to use the SUPERLU matrix type with the 
MatMatSolve() routine.

I changed a working code (which uses MatMatSolve()) by the setting the 
matrix type to superlu (using MatSetType()) and now I get the following 
runtime errors in MatMatSolve():

[0]PETSC ERROR: Null argument, when expecting valid pointer!
[0]PETSC ERROR: Null Object: Parameter # 1!
