Hello, (sorry for the mess in the previous message)
Unfortunately (unloke for Hagen Fuchs) upgrading all *avahi*-packages to 0.6.31-2 in wheezy did not solve the problem for me. I have still the same symptoms I reported for 0.6.31-1. Only with the patch applied to 0.6-31-2, the problem goes away. Regards, Otmar
