           Summary: M3UA version 5 packet dissecting issue
           Product: Wireshark
           Version: 1.1.x (Experimental)
          Platform: Other
        OS/Version: Windows XP
            Status: NEW
          Severity: Major
          Priority: Medium
         Component: Wireshark

Build Information:
Paste the COMPLETE build information from "Help->About Wireshark", "wireshark
-v", or "tshark -v".
I am developing Wireshark on V1.1.3. 
In epan/dissector/packet-m3ua.c, I have found M3UA_RFC, M3UA Ver 5 dissector
are impletemented in source code actually. 

I set the "version" in line #324 to be M3UA_V5, which is originally M3UA_RFC,
and then compile it, passed.

But when I tried to decode a M3UA Ver 5 message, it reports "malformed packet".
The common header of M3UA V5 is decoded correctly, but the network appearance
parameter, it could not decode any more. 

I am sure that the testing packet is correct because I compare the packet with
the M3UA Ver 5 protocol itself. 

Now I am wondering where is the bug. I need to dissector M3UA Ver 5. 

Thanks and waiting.
M3UA V5 protocol and my test packet are attached.
