Thanks Tristan.

Apparently, inside gnome_canvas_item_new, the ref_count gets incremented
three times (to 4), and decremented again to 2, which is fine. The unref
decrements again to 1, which is also correct.

The sentence:

     gtk_object_destroy(GTK_OBJECT(img_item));

Does not destroy the pxb item - the ref_count is not changed to 0... I
scanned over the gnomecanvas.c code, but I cannot find any code for
unreferencing the pixbuf... But then I'm not a great programmer and not
faniliar with the gnome insides.

Should I report this as a bug?
