Jan Stránský proposed the following answer:
Ok, I have found the problem.

> Apart from the wall using the frictmat

the problem is that FrictMat is actually not used:

>for b in O.bodies:
> if random.random() < 0.5:
>  b.mat = mat1
> else:
>  b.mat = mat2

here you set materials of all bodies to CohFrictMat. Than between Box an
Sphere, ScGeom is created, but Ip2_CohFrictMat when setCohesionNow is
set consideres ScGeom6D, caousing the segmentation fault.

preserve FrictMat on boxes like following
###
for b in O.bodies:
  if not isinstance(b.shape,Sphere): # change material only on spheres
continue
  if random.random() < 0.5:
...
###
and the code should work (works for me)
cheers
Jan

Strange, I tried it now and also got segmentation fault, too..

below see valgrind output in case it help for somebody. The error occurs
at the beginning of the last O.run command
