Comment # 1 on bug 11841 from 
Crashes here :
https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob;f=asn1/nbap/nbap.cnf;hb=HEAD#l1458

conversation_get_proto_data(old_conversation, proto_fp) returns a NULL pointer,
the reference in memcpy crashes it. I was able to make it go away by changing
the previous line to 

if (old_conversation && conversation_get_proto_data(old_conversation,
proto_fp))

but I don't think that's the correct fix. I don't know enough NBAP to say if
that's affecting the output either, need someone else to chime in .
