This bug also presents itself on OpenBSD/macppc. I have tracked down where the     
bad format_code is created, however I don't know the proper fix for this.     
The bad format_code is created in _get_image_surface() in cairo-xlib-surface.c    
around line 532 when surface->visual is not 0. I see the masks struct filled in    
with bpp = 8 alpha_mask = 0 red_mask = 0 green_mask = 0 blue_mask =0. The call   
to _CAIRO_MASK_FORMAT call returns False, then   
_cairo_image_surface_create_with_masks is called which in turn calls   
_cairo_pixman_format_create_masks which creates the format_code of   
0x8010000 which is unrecognized by fetchProcForPicture.   
A fix or work-around for the problem would be very much appreciated. It is 
holding up firefox 1.5 on OpenBSD.
