By either
1) capturing either on Ethernet or a PPP interface on an OS
where libpcap supplies PPP packets as PPP or fake Ethernet
packets (note that Linux is *NOT* such an OS);
2) if you are capturing on one of those, getting a newer version
of Ethereal (it didn't handle some types of PPP captures with
PPP headers in some older versions);
3) patching the TCP Graph code to use the "tap" mechanism rather
than parsing of the link-layer, IP, and TCP headers itself;
4) patching the TCP Graph code to handle the link-layer headers
for the type of network on which you're capturing.
If you do 3) or 4), send us the patch.

The error message needs to be changed to be "Selected packet is not a
TCP segment on Ethernet, PPP, or raw IP", or something such as that.
