Ok, I have found out how to work around the problem so this might help a
developer figure out why it is happening. I have a SYMBOLSET file with
the shield symbols defined as follows. I will also note that is does not
occur at all zoom levels within the LAYERs scale range. Maybe the symbol
is getting bumped out in the drawLabelCache so it doesn't get executed.
