Comment # 1 on bug 9894 from 
I can reproduce this. The crash is in packet-rtp.c

encoding_name_and_rate_pt = (encoding_name_and_rate_t
*)g_hash_table_lookup(p_conv_data->rtp_dyn_payload, &payload_type);

the hash table seems to be corrupt, e.g. the key comparison function is NULL

I couldn't figure out where the hash table gets corrupted. The hash table is
already broken when packet-rtp reads it as part of 


 p_conv_data = (struct _rtp_conversation_info
*)p_get_proto_data(wmem_file_scope(), pinfo, proto_rtp, 0);


The hash table is created in setup_sdp_transport() and passed to the rtp layer
via
(s)rtp_add_address()...
