I just verified that the GdkDirectFB patch alone doesn't cause the bug, 
so its recent commit was ok.
The bug i ran into (try closing the "icon view basic" window in 
gtk-demo, trace attached) was istead caused by window_flip_group.patch 
and is triggered only when NO_EXPERIMENTS is *not* defined, otherwise 
the patch is ok.
I'll do more testing tomorrows.
