Daniel,

- AFAIK iptables is there by default with the Ubuntu Lucid server on
the host (iptables -L confirms).
- Honestly I don't know if it gets ICMP redirect when SSH X forwarding
is started in the container. I couldn't find any clue on my system or
reference on the Internet to this happening.

Considering the fact that I don't experience the crash in the same
environment with the same installation and setup on other type
machines I tend to believe that the problem is some odd lower level
(driver/bios) issue related to the type of HW. Arie advised  to try
fwts to see if it shows anything obvious.
I've run it but it keeps segfaulting. I'd need to spend some more time with it.

Let me know if there is anything else I could try to help the investigation.

Regards,
Ferenc
