I did some more research and found that only the OIDs defined as OID:
SNMPv2-SMI::zeroDotZero will give this error.
ie. IF-MIB::ifSpecific.1 = OID: SNMPv2-SMI::zeroDotZero

I've done a bit of poking about, and suspect that the Net-SNMP subagent may
be returning an invalid encoding of .0.0 within the AgentX packet.

Can you please try the enclosed patch, and see if it makes any difference.
