Problems using external packages Spooles and Hypre with PETSc v2. 3.1

I have been having (patch 9). I was not having these problems with
PETSc v2.3.0. 

I am using Spooles downloaded from the PETSc ftp site and built into
PETSC_DIR/externalpackages. When solving a partcular problem I am getting
the error:

MatFactorNumeric_MPIAIJSpooles line 199
MatLUFactorNumeric line 2200 src/mat/interface/matix.c
KSPSetUp line 183 src/ksp/ksp/interface/itfunc.c
KSPSolve line 305 src/ksp/ksp/interface/itfunc.c

The problem also occurs in serial.

I am using Hypre v1.10.0b downloaded from the LLNL site and built separatly
to PETSc. When I have been using Pilut and Parasails as either global
problem preconditioners of as sub preconditioners for ASM or BJACOBI, I have
been getting errors indicating that there could be a memory access out of
range. I suspect that there may be a memory overwrite or mismatch occuring
somewhere. Note that BOOMERAMG and EUCLID seem to work OK. Again these
problems were not apparent when I was using PETSc v2.3.0.  

Have there been any significant changes in the PETSc source that handles
Spooles and Hypre between versions 2.3.0 and 2.3.1 that could be causing
these problems? I don't really want to go back to using PETSc v2.3.0 if I
can help it. I don't know if it makes any difference, but I am using the
Fortran interface to PETSc.

Hope you can help.
