Wireshark · Ethereal-dev: [Ethereal-dev] error with one dissector....help

[david martinez <davidmfcg@xxxxxxxx>]

Hi; i'm created a dissector to a simple protol with
only 1 field; but when i have instaled ethereal 0.14
and i open a capture file where should be appear my
protol tree appear this error:
  [Dissecotr bug protocol LLCTLB: proto.c:1187 failed
assetion "(guint)hfindex <gpa.hfinfo.len"]
On COL INFO appear that message too, but appear the
name of my protocol too, on PROTOCOL_INFO apprear the
name correct too. What is my problem?? I put here my
code, please somebody help me:
