FYI - not fixed; could some SIP expert have a look at this?

Recreated on Linux with Ethereal 0.10.3:

Enclosed:
backtrace.txt: gdb  backtrace
fail.cap: a single SIP packet (packet 8 in original file)
sip.binary: The TCP payload from that packet
whole.binary: The whole frame of that packet

.binary files are created by "export selected packet bytes"
I suspect sip.binary can be read with a text editor - seems to work 
here, but I don't know SIP.
