I've had an opportunity to spend a few minutes looking at this.

case1.xml contains no <upnp:artist> XML tag for the Artist, but it does contain AlbumArtist information as follows:

<upnp:artist role="AlbumArtist" xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/">Johnny Cash</upnp:artist>

case2.xml also contains no <upnp:artist> XML tag for the Artist, but it does contain Composer information as follows:

<upnp:artist role="Composer" xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/">Stan Jones</upnp:artist>

Does the first track have an AlbumArtist tag, and does the second track have a Composer tag? If so, it would seem that the inconsistency you are seeing is caused by the control point's interpretation of correct XML data sent by MinimServer.
