Hmmm, like when (besides retransmission)?  It certainly is ugly to look at.

BTW, I also mean to check if the SCTP dissector should be catching 
exceptions whenever calling a subdissector.  What I fixed above was 
causing me massive confusion because the peer was SACKing TSNs I 
couldn't see in the trace (because M3UA exception'd out).  Of course 
exceptions may occur for other reasons and we should never forgot to 
display all the DATA chunks.
