gnome-theme-manager high cpu usage

[Michael Guterl]

I am getting extremely high CPU usage when running gnome-theme-manager
under hoary.  When run from console this message is repeated over and
over again.

(gnome-theme-manager:5055): GdkPixbuf-CRITICAL **:
gdk_pixbuf_composite: assertion `dest_x >= 0 && dest_x + dest_width <=
dest->width' failed
art_render_invoke: no image source given

FWIW I am not using the default ubuntu kernel, but I'm compiling an
unpatched 2.6.9 kernel to make sure I can recreate.

There's the output of top just for reference.
