The backtrace has been added to the filter, it happens at line
#549. Leaving us with two possibilities for problems:

stats_prefix == NULL

pp->key == NULL

   542			case 2:
   543			    fprintf(fp, "%s%f  %s\n", stats_prefix, pp->prob, pp->key);
   544			    break;
   545			case 3:
   546			    fprintf(fp, "%s%f  %f  %s\n", stats_prefix, pp->prob, spamicity, pp->key);
   547			    break;
   548			default:
   549			    fprintf(fp, "%s%f  %f  %f  %8.5e  %s\n", stats_prefix, pp->prob, product, invproduct, spamicity, pp->key);
   550			    break;
   551		    }
   552		}
   553	    }
   554	
   555	    return spamicity;
   556	}
