segmentation fault while specifying an Experimental Cell Size Distribution

[vishalnp37]

HI I am trying to simulate a microstructure of melt and while using Laguerre tessellation ,as a sample, I created a .txt file called mydistrib.txt which contains
0.2 10.0
0.3 20.0
0.4 5.0
when I try to run :

neper -T -n from_morpho -morpho "diameq:custom(mydistrib),1-sphericity:lognormal(0.145,0.03)" -statcell diameq -o mytess

It is giving me a segmentation fault

Use the full file name: diameq:custom(mydistrib.txt), not just diameq:custom(mydistrib).
