pdfsig - Segmentation fault (core dumped)

Wen i use pdfsig to validate a pdf digital signature i get this error "Segmentation fault (core dumped)". I checked log and there is this message "pdfsig[6529]: segfault at 38 ip 00007fb64486a824 sp 00007ffcf4361240 error 4 in libnss3.so[7fb644810000+13c000]"

What can i do to correct this error?
