The curious thing is mythfrontend --version gives the same information
for both packages, so I'm not sure where any incompatibility would be
coming from.

mythfrontend --version (on both machines):
MythTV Version   : Unknown
MythTV Branch    : branches/release-0-21-fixes

mythbackend --version (on the master backend):

I ran mythtv-setup on the master backend and it had the proper IP.  The
frontend machine with the problem is a frontend *only*, so it doesn't
have mythtv-setup; however, I deleted the config.xml file and manually
reconfigured mythfrontend on it to  make sure it had the proper IP.

The frontend on the working machine has 'localhost' for its DBHostName,
but I didn't configure that one.  I can't seem to manually reconfigure
it; if I delete the config.xml file it just automatically reconfigures
itself with localhost without asking me.

This worked fine before I upgraded the package.  Is it possible for two
mythtv versions that report the same version numbers to have hidden
incompatibilities?  Is Packman just distributing a bad build?  I'm
afraid to try upgrading the master backend for fear I'll break that one,
too.
