When decoding a JSON message with a member name that is a UTF-8 string that has
been trunkated in the middle of a multi-byte sequence (in my specific case: e2
85 9c ec b7 94 ed bf ba e3 83 9b eb 8a 91 e4 b5 be ed 85), the following
message is shown in the frame dissection tree after the "JavaScritp Object
Notation" item:
[Dissector bug, protocol JSON: proto.c:2554: failed assertion
"g_utf8_validate(value, -1, ((void *)0))"]
