Looks like incorrect data manipulation at ofl_utils_count_ofp_queue_props function in oflib/ofl-structs.c. At debug print we can see incorrect value in prop->len at second step of while-loop:

data_len=48, ntohs(prop->len)=16, sizeof(struct ofp_queue_prop_header)=8
data_len=32, ntohs(prop->len)=2, sizeof(struct ofp_queue_prop_header)=8
