Description of problem:
When ipv6 networking is up (both for lo and eth0), I get 
...
unreachable 3ffe:ffff::/32  metric 1024  error -101 mtu 16436 advmss 16376 metric 10 4294967295
Segmentation fault

when I execute either
/sbin/ip -6 route show dev lo via ::
or
/sbin/ip -6 route show dev eth0 via ::
.

The segfault happens every time I run /sbin/ip -6 route show dev lo via ::.
It also happens sometimes when the initscripts shut down networking.

Version-Release number of selected component (if applicable):
iproute-2.6.11-1

How reproducible:
Always

Steps to Reproduce:
1.have at least one network card installed
2.set up 6TO4 as in /usr/share/doc/initscripts-8.11.1/ipv6-6to4.howto
3.bring up the network including ipv6
4.execute /sbin/ip -6 route show dev lo via ::
5.it segfaults
