Bug Description

Binary package hint: iproute

iproute: 20071016-1
linux-image-2.6.24-12-xen: 2.6.24-12.22
xen-hypervisor-3.2: 3.2.0-0ubuntu9

uname -a: Linux hostname 2.6.24-12-xen #1 SMP Thu Mar 13 00:19:55 UTC 2008 x86_64 GNU/Linux

# tc qdisc
Segmentation fault

# tc qdisc show dev eth0
Segmentation fault

# tc -s qdisc show dev eth0
Segmentation fault

I'd note that this is a release critical bug. You can't release an OS with bugs in the iproute package and expect people to use it.
