Yes, the network bridge scripts have problems parsing iputils output
in some circumstances it seems.

In Kai's case, I believe it was because he had multiple default
gateways with different weights, and ip route would show:

default via 192.168.1.1 dev eth0  src 192.168.1.231

When the scripts were expecting:

default via 192.168.1.1 dev eth0

Since I am using the xen.org 3.2 rpms on my system it was very
hard to properly troubleshoot, so that might not be the bottom
line here.
