Comment (by trevorwekel):

 The following modifications have been make to query algorithm:

 - Only perform the query if a selection area can be calculated.  If the
 input geometry is a line, a centroid cannot be calculated.  This typically
 occurs outside of coordinate system bounds.
 - Intersect the selection area with the map extent and only process the
 query if the intersection exists.
