[mythtv] problems talking to MBE with svn 22176

[Simon Kenyon]

just built trunk svn #22176 and i am getting errors when trying to 
connect to my MBE:

2009-10-02 20:24:18.654 MythContext: Connecting to backend server: 
195.7.61.35:6543 (try 1 of 1)
2009-10-02 20:24:25.677 MythSocket(84170d0:28): readStringList: Error, 
timed out after 7000 ms.
2009-10-02 20:24:25.677 Protocol version check failure. The response to 
MYTH_PROTO_VERSION was empty.

FE and MBE were both built this evening from 22176

any ideas?
