Title:
  Compiz crashes when iconifying window with applied input mask

Status in Unity:
  Won't Fix
Status in compiz package in Ubuntu:
  Won't Fix
Status in unity package in Ubuntu:
  Won't Fix

Bug description:
  This crash happens for me always when I apply input mask to a window
  and trying to iconify this window (even with alt+space menu)

  
  I've attached a simplified test case which reproduces the issue
  To run:
   gcc main.c `pkg-config --cflags --libs gtk+-2.0` -o main && ./main

  It uses gdk_window_input_shape_combine_region() to apply input mask,
  but if you rewrite an app to use gtk_widget_input_shape_combine_mask()
  or  XShapeCombineMask() (with ShapeInput parameter) compiz will crash
  as well.

  
  Ubuntu 13.04
  Compiz 0.9.9.0
  What you expected to happen:
      Successful iconification of a window
  What happened instead:
      compiz crashed

  I am able to reproduce this issue on Ubuntu 13.04, 13.10.  It works
  fine for me on Ubuntu 12.04, I did not try 12.10.
