It was a security release r1376 of the same version on june 10.
I was running the first stable version 0.2.4
The config file contains the same password I was using.
The mt-daapd.conf is placed in /etc.
When I move the config file and start mt-daap it syas it can not find the config file. So the one where the password is in is the right one.
In the meantime I went back from a backup disk to my previous version.
I copied the mt-daapd binary but that did not help. After copying the everything in the package list it all runs again.
