The effect uses command line arguments to determine the bounding boxes.
>From the 0.44.1 release notes:

     * The --query-* command line parameters now return the true SVG
       bounding box of the object instead of the Inkscape coordinate
       system bbox (with inverted Y axis). The new behavior makes more
       sense for scripting use of Inkscape.
