It is not exactly the same as the .png image above, as for that one I made some adjustments in the Gimp. Also, I noticed that Inkscape and Gnome do not render the image exactly the same, particularly the shadows and when displayed small.In the Gnome panel I would say the .png image would do better, but for the program icon the .svg might work fine as well.
What exactly are you using the file for? When I know, I could still tweak the image a bit for that purpose.
