Bug#605507: icecast2 failed to reinstall/upgrade/purge

[Alessio Treglia]

Package: icecast2
Version: 2.3.2-5
Severity: serious
Tags: sid squeeze

This bug was originally reported on Launchpad, see https://launchpad.net/bugs/481060 for more information.
I've reproduced this in an AMD64 sid chroot, dpkg's terminal log follows:

---

Steps to reproduce (on squeeze/sid):

1. aptitude install icecast2
2. Run icecast2:
  a. Modify /etc/default/icecast2 and set ENABLE to true
  b. /etc/init.d/icecast2 start
3. aptitude purge icecast2 OR aptitude reinstall icecast2


Although I have not performed any upgrade test, I bet it would happen on upgrade too.
