Wireshark-dev: [Wireshark-dev] issue to set up an RTP conversation

I've a dissector (packet-ua3g) that calls rtp_add_address(...) to set up an RTP conversation.
It was working but now it fails. I've checked on master, 3.0.0 (windows) and 2.6.6 (ubuntu 14.04)

I've found it's due to pinfo->fd->visited being already set (strp_add_address(...) function)  that
prevents the conversation to be added.

     * If this isn't the first time this packet has been processed,
     * we've already done this work, so we don't need to do it
     * again.
    if ((pinfo->fd->visited) || (rtp_handle == NULL) || (rtp_rfc4571_handle == NULL))

I can workaround by clearing the "visited" bit before calling rtp_add_address(...) but I don't think

it's correct...

Any comments?
