PETSc: Segmentation Violation

Hello,

thanks for the efforts on SfePy and even adding a parallel solver. Unfortunately, the parallel examples don't work for me. I've tried with petsc4py 3.6.0 and PETSc 3.6.0 as well as 3.6.1.

I appned the error message from the command "python examples/multi_physics/biot_parallel_interactive.py output-parallel". When run in parallel the message is basically the same, but multiple times.

Best regards
