Comment 28 for bug 1284391

stripes_in_rect_plain.svg worked for me with the patch and r13120. Note that normally if the mouse pointer is anywhere over the Inkscape window "top" usually shows 1 or 2% cpu, depending on where it is hovering. Load one of the toxic files and place the pointer off the Inkscape window and this goes to zero when the patch is applied, but will be a significant number (15%, 30%?) otherwise, even though the mouse is out of the picture (so to speak).
