Some hours later ... 5 is the value for ASN_NULL !

#define ASN_NULL            ((u_char)0x05)

asn1.h [1] from net-snmp define this constant. Some snmpgets return
null value. A tcpdump later, I found some oids not known by equipment
so null value is returned.

Is it possible to have oid included in message for this type log ? I
can be useful to find quickly the wrong data.
