art_render_invoke: no image source given

[Rob Benton <rob benton conwaycorp net>]

I couldn't find any reference to this in the archives or on the gnome 
bugzilla.  Google yielded 2 bugs in Debian but no cause or solution.

It looks like this line of code:
===========================================================
GError * err = NULL;
Glib::RefPtr<Gdk::Pixbuf> pb = 
Glib::wrap(gdk_pixbuf_new_from_file_at_size("path/to/image.svg", width, 
height, &err));
===========================================================

is causing this output when I run:
===========================================================
art_render_invoke: no image source given
art_render_invoke: no image source given
art_render_invoke: no image source given
art_render_invoke: no image source given
art_render_invoke: no image source given
art_render_invoke: no image source given
===========================================================


But I have that code in 2 places and only 1 of them is creating this 
output.  Is this a known issue or something?
