[mythtv] database upgrade error in latest cvs?

[Peter Lee]

Isaac, Bruce:

Thanks for the help.  As you both suggested, I dropped the columns in
question and started the backend.  My intention was to report back to
you with the error messages that ensued.  Unfortunately, there aren't
any!  Everything is working again!

So, while I am happy (actually, my wife is even happier ;-) this
doesn't seem to give me any answers as to what happened.  Looking
through libs/libmythtv/dbcheck.cpp, my guess is there was race
condition in the db schema upgrade between the master and slave.  My
suspicion is that I started the master and managed to check its status
and then start the slave backend, all before the master finished the
db upgrade.

Does that make sense?  Looking at the code, I'm not sure why this
would cause a dbver skew, so perhaps my guess is wrong...
