I'm note getting this error. My guess is that it is coming from the
final lines of backend_gtk.py

# set icon used when windows are minimized
if gtk.pygtk_version >= (2,2,0):
    basedir = matplotlib.rcParams['datapath']
    fname = os.path.join(basedir, 'matplotlib.svg')
    try:   gtk.window_set_default_icon_from_file (fname)
    except gobject.GError, exc: print >>sys.stderr, exc

My win32 pygtk is older than 2.2.0 which may be why I am not seeing it.
Would you mind seeing if this is indeed the problem (for starters,
just replace the conditional with 'if 0:'.  If you get any more
insight into the problem, be sure and let me know!

Also, Steve, we might be better off here catching *all* exceptions
rather than just the gobject error.  Darren, would you test to see if
this works


# set icon used when windows are minimized
if gtk.pygtk_version >= (2,2,0):
    basedir = matplotlib.rcParams['datapath']
    fname = os.path.join(basedir, 'matplotlib.svg')
    try:   gtk.window_set_default_icon_from_file (fname)
    except: print >>sys.stderr, 'Could not load matplotlib icon'


FYI

C:\Program Files\Common Files\GTK\2.0 # looks like the default registry path

/lib/gtk-2.0/2.2.0/loaders/svg_loader.dll # looks like a path from pkgconfig
