MemoryError on sequencegraph

Guessing this is not a captcp problem, but wondering if you have some tips? Trying to run this on OSX.

$> python captcp.py sequencegraph -v debug -i 1 -l 192.168.0.199 ~/Desktop/archive.pcap

Cairo issue / bug? pcap file: http://dl.dropbox.com/u/2132185/archive.pcap

Hey Ilya, maybe try to reduce archive.pcap, e.g. tcpsplit the pcap file?

Can you upload the pcap file? I will try to reproduce the error.

http://dl.dropbox.com/u/2132185/archive.pcap - should be it. seems to be crashing on small files also, I suspect its my cairo install (ugh).

Tends to be. The raised python error highlight a s

Cairo error. Can you try to boot Linux and reproduce the error?
