Comment # 3 on bug 9885 from 
Notes to self:

The reason the RTP packet matches a conversation (which it shouldn't) is
because RTP dissector sets up a wildcarded conversation... but conversations
have no concept of wildcarding sources vs. destinations really - the
conversation matching logic will match a packet to a wildcard entry based on
its source addr:port OR its dest addr:port. So here we have a packet of a
source addr:port that matches a wildcard entry, even though RTP really intended
it to be a *dest* addr:port wildcard entry only.

Unfortunately, if this is fixed (ie, if conversation matching is enhanced to
offer specifying only match wildcard for a specific direction), that will break
our ability to decode RTP from SIP latching scenarios. So this behavior is ok.

Also, the stack trace above is misleading - the line numbers for packet-rtp.c
are a bit off as I ran that with debug printing code that doesn't exist in
master.
