Hello. During dump analysis I found that Wireshark can’t parse DIAMETER packet properly:

[Dissector bug, protocol DIAMETER: proto.c:1044: failed assertion "DISSECTOR_ASSERT_NOT_REACHED"]

(source line can be different different, because I tried versions 1.08, 1.13 and 1.20 pre1 and don’t remember the exact version-line number)

I made some analysis and found that it can be fixed by editing TGPPGmb.xml file in "diameter" folder by removing the following entry:

 <avp name="3GPP-Charging ID" code="2" mandatory="must" may-encrypt="yes" protected="may" vendor-bit="must" vendor-id="TGPP">

      <type type-name="Integer32"/>

    </avp>

It fixed the error, but DIAMETER AVP fields still can’t be parsed properly, i.e. AVP code 904 still can’t be displayed, but it does exist in TGPPGmb.xml.
