It looks like avahi.daemon gets stuck while registering (well, I know this is not really a good way of debugging at all, maybe someone has better suggestions?)
Directly after booting:
stefan@silmaril:~$ ps axf | grep avahi 5431 ? Ss 0:00 avahi-daemon: registering [silmaril.local] 5432 ? Ss 0:00 \_ avahi-daemon: chroot helper 6418 pts/0 S+ 0:00 \_ grep avahi
stefan@silmaril:~$ sudo /etc/init.d/avahi-daemon restart * Restarting Avahi mDNS/DNS-SD Daemon: avahi-daemon [ OK ]
stefan@silmaril:~$ ps axf | grep avahi 6533 pts/0 S+ 0:00 \_ grep avahi 6525 ? Ss 0:00 avahi-daemon: running [silmaril.local] 6526 ? Ss 0:00 \_ avahi-daemon: chroot helper
(after restarting, all apps using avahi work again)
