Matt,

I presume this is a flaw in my implementation of raster query.  I would
appreciate your filing a ticket with a small, easy to reproduce test case
for me.  ie. a map file with two small raster files as layers, and
the mapserv url (like above) to invoke the request.  Assign the ticket
directly to me (warmerdam).

Best regards,
