Piotr,

I have tried the latest version v7.12.5 and it is working quite well, 
even themes download now works! The only changes I have made to 
config.txt are to set disable_overscan=1,hdmi_group=1,hdmi_mode=31 (50Hz 
1920x1080p).

I had the same problem as Peter Bennett with initial setup Country 
Language, I just created a config.xml and rebooted -everything worked at 
this point. Attached is zipped log file.

I have 3 mythtv backends on my network, all of which showed up as 
"firewall".
The 3 backends are:
a) Mythbuntu 14.04 running 0.28pre ppa.
b) Ubuntu 15.10 running 0.28pre ppa
c) Debian Jessie running mythtv built from git master (0.28)

I suspect the inital setup problem may be due to myth-backend settings 
and/or ipv4/v6 issues and possibly mysql bind addresses. My network is 
ipv4. Can you post your myth-backend setting relating to ip addresses, 
link local settings, together with your mysql bind address.
