Bug#517360: programs fail with ../sysdeps/posix/getaddrinfo.c:1457: rfc3484_sort Assertion .. failed

[Soeren Sonnenburg <bugreports@nn7.de>]

Package: libc6
Version: 2.9-3
Severity: important

Note, this happens to me with python, sudo and several other programs

$ sudo
sudo: ../sysdeps/posix/getaddrinfo.c:1463: rfc3484_sort: Assertion
`src->results[i].native == -1 || src->results[i].native == a2_native'
failed.
Aborted

Googling around I found that this is bug 317824 in ubuntu
https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/317824

As in the report I can fix it by commenting out a few lines in
/etc/hosts.
