gran/hooke/history/stiffness crash

Hi,

I am trying this out this pair style:

pair_style gran/hooke/history/stiffness
pair_coeff * *
fix m1 all property/global kn peratomtypepair 1 1.e8
fix m2 all property/global kt peratomtypepair 1 1.e8
fix m3 all property/global gamman peratomtypepair 1 0.1
fix m4 all property/global gammat peratomtypepair 1 0.1
fix m5 all property/global coefficientFriction peratomtypepair 1 0. # DOES NOT WORK!

The last property causes this crash:

I have created a small example to illustrate this problem. See attached file.

Any ideas? I downloaded the version of LIGGGHTS directly from this website just several days ago.

Thanks,
