The minimal difference used in the space comparison was just recently
increased from 16kiB to 2MiB.  Unfortunately, yours is showing a
difference of about 29MiB.  See
http://svn.mythtv.org/trac/changeset/14924/trunk/mythtv if you want to
see how to increase it to 30MiB...

I can't help with this part, either, though I think that figuring out
the answer will allow you to fix the issue properly (either on your
system configuration, or--if necessary--in Myth).
