Sudoku startup error

[Tom Smith]

I'm not quite sure where to start looking for a solution to this
problem. I looked up the error via google and wasn't able to find a
solution. Here's the error:

Traceback (most recent call last):
  File "/usr/games/gnome-sudoku", line 10, in ?
    from gnome_sudoku.gnome_sudoku import start_game
  File "/usr/lib/python2.4/site-packages/gnome_sudoku/gnome_sudoku.py",
line 17, in ?
    pb = gtk.gdk.pixbuf_new_from_file(os.path.join(IMAGE_DIR,filename))
gobject.GError: Couldn't recognize the image file format for file
'/usr/share/gnome-sudoku/Footprints.svg'

Can anyone offer any suggestions for solving this problem? Thanks in
advance for your help.
