Hi,
Could you possibly show us the whole LAYER from your mapfile and one
GeometryCollection as WKT? Perhaps someone gets interested in making some
trials.
Do you feel that there is something odd with your sample SQL? For me it looks
like your GeometryCollection has one point, one linestring and one polygon and
your query correctly finds them all one by one.
