Seg Fault using offscreen patch

[iluvlinux <iluvubuntu gmail com>]

hi
  i am trying to use the offscreen patch that is  available at 
http://bugzilla.gnome.org/show_bug.cgi?id=318807
http://bugzilla.gnome.org/show_bug.cgi?id=318807 
 
some times i get segfault while pressing a button or checking a check box (i
have tried with these two widgets till now)

Actually i am trying to use a clutter-stage embedded in a GtkWindow and than
i take snapshot of the window and try to display it on clutter stage. 

heres is the gdb o/p

Continuing.
