I used to have "/mythtv/store" on each backend.  About two months ago,
I changed that to:

/mythtv/topaz on the master
/mythtv/cobalt on the slave

Then gave the frontend the ability to see each of those via nfs.

When this problem first poped up, I removed the frontend's ability to
see those paths, just to make sure that was not causing the problem.
It did not make any difference.

I updated to the svn head at the end of last week to play with the new
mythsocket stuff.  Before that, it had been 3 weeks since I updated
from svn.  This problem started at the end of last week.
