libcec-daemon fails to start without specifying HDMI port

Starting at the commit of Jan 16, 2014 libcec-daemon fails to start in my setup. I use libcec 2.1.4 and have a Samsung Series 6 TV, connected to the Pulse Eight adapter.

The daemon stops with failure "Failed to become active". It took me several hours debugging to realize the problem is that it couldn't detect the physical address. If I specify the port, it's starting OK.
1. Is the detection mechanism broken? It seems to be working fine on older versions.
2. I think libcec-daemon should log a warning or error if the physical address is not detected and perhaps show a hint that you have to specify it manually.
