My frontends definitely don't want to connect to the backend when
mythfilldatabase is running:

2008-05-31 20:02:46.581 XMLParse::LoadTheme using
/usr/share/mythtv/themes/metallurgy/ui.xml
2008-05-31 20:02:46.893 Connecting to backend server:
192.168.1.50:6543 (try 1 of 5)
2008-05-31 20:02:53.900 MythSocket(999c40:18): readStringList: Error,
timeout (quick).
2008-05-31 20:02:53.900 Unexpected response to MYTH_PROTO_VERSION:

Recordings page shows "There are no recordings available"

The backend log (with important,general,socket,schedule verbosity) at
the same time:

2008-05-31 20:02:07.345 MythSocket(919450:17): UpRef: 3

2008-05-31 20:03:01.329 MythSocket(2aaaac088f00:20): cb->readyRead()

and finally, the mythfilldatabase log (or, at least, the end of it):
