Argh! I've reproduced the problem, carefully created the log files, 
anonymized them and was just going to post them when it hit me after 
I've read the first line of the copy&paste of the log, which was:

[2005-09-20  20:52:50] INFO main/main Icecast 2.2-kh9 server started

I have deployed version 2.2-kh9 again, instead of the newly built rc3! 
(The build machine and the deployment machine are different)

So I slap myself on the head, installed the rc3 and _everything_ works 
as intended.

Sorry for bothering and thanks for the help !
