OK, I did it for you and the RANAP dissector seg faults.

I am submitting a patch for that problem but that's not going to help you
because the dissector thinks that the message has extensions.

I have attached the text file I used with text2pcap so people have an
example.  In this case I just stuffed the RANAP message into an ANSI SCCP
Unitdata message.  M2UA should be set to Draft 7.

I have attached the text2pcap output that will cause a "stock" ethereal
to crap out.

I have attached a small working RANAP file, this particular one needs
MTP3 set to Chinese ITU, and M2UA set to Draft 7.  It contains one
RANAP Initial UE Message with an embedded DTAP Location Update Request.
