I found the problem, but I don't know if my database is broken somehow. The 
master server is set to a hostname, for some reason. The problem is with 
getMasterBackend() in src/mythbox/mythtv/db.py . My database has:
+-----------------------------------+-------------------------------------------
--------------+------------------------+
| value                             | data                                      
              | hostname               |
+-----------------------------------+-------------------------------------------
--------------+------------------------+
| MasterServerIP                    | blackhole.lan.fa2k.net                    
              | NULL                   |
| MasterServerPort                  | 6543                                      
              | NULL                   |
| BackendServerIP                   | 127.0.0.1                                 
              | blackhole.lan.fa2k.net |
| BackendServerIP6                  | blackhole.lan.fa2k.net                    
              | blackhole.lan.fa2k.net |

So problem #1 is MasterServerIP doesn't match any BackendServerIP. I changed 
the SQL string to
            sql = """
                select 
                    c.data as ipaddr,
                    b.data as port,
                    c.hostname as hostname
                from 
                    settings a, 
                    settings b,
                    settings c
                where 
                    a.value = 'MasterServerIP' and
                    b.value = 'MasterServerPort' and
                    c.value = 'BackendServerIP' and
                    c.hostname  = a.data
                """
Don't know if this is a general fix or if it introduces other bugs. 

At this point I got a different error while connecting and these messages in my 
mythbackend log,
2013-07-01 23:07:50.657000 C  MainServer::HandleVersion - Client speaks 
protocol version 8 but we speak 75!
2013-07-01 23:07:50.657084 W  MainServer: Unknown socket closing 
MythSocket(0x21937c0)
2013-07-01 23:07:50.658389 W  MainServer: Unknown socket closing 
MythSocket(0x2190ed0)
2013-07-01 23:07:53.582574 W  MainServer: Unknown socket closing 
MythSocket(0x20c3f50)

Now I'm giving up..

(Seems that it would introduce bugs if MasterServerIP is indeed an IP address 
and the hostname column is a hostname)
