Comment 10 for bug 1293252

I still get the crash even after removing the window-list applet. I actually just finished building libwnck3-3.4.7 with this line commented out in libwnck/xutils.c in the try_pixmap_and_mask() function, and it successfully prevents the crash. I haven't noticed any side-effects other than some errors logged to my terminal:

  if (mask_surface)
    {
      //XXX cairo_mask_surface (cr, mask_surface, 0, 0);
      cairo_surface_destroy (mask_surface);
    }
  else
    cairo_paint (cr);
