From Sean Van Gorder: 

When Wireshark attempts to read an SNMP packet with a variable-bindings item
with an OID containing an index string which includes an entry of type
"Unsigned32", Wireshark will stop dissecting the packet at this index entry and
end with the error:

[Dissector bug, protocol SNMP: proto.c:2761: failed assertion
"DISSECTOR_ASSERT_NOT_REACHED"]
