 I have a mysql.txt as follows.

 {{
 DBHostName=localhost
 DBUserName=mythtv
 DBPassword=password
 DBName=mythconverg
 DBType=QMYSQL3
 }}

 When the backend tries to startup it fails to connect to mysql because it
 attempts to contact it on the ipv6 localhost address (which mysql doesn't
 even
 support before 5.5). Logs are as follows

 You can see mythsocket attempt to connect to the incorrect address
 MythSocket(2008ac0:0): attempting connect() to (0:0:0:0:0:0:0:1:3306)
 which immediately fails because mysql isn't listening there.

 I've worked around the issue for now, by setting DBHostName=<hostname>
