Bug Description

Unity/compiz crashes with the debug output pasted below. This happens consistently with the following steps:
1. Open CompizConfig Settings Manager, check 'Override Theme settings' in the Unity plugin under the 'Decorations' tab
2. Maximize a windows application running under Crossover; Word 2010 and Powerpoint 2010 tested
3. Unmaximize the Crossover application

System details:
- Ubuntu 16.10
- Unity: 7.5.0+16.10.20160906.1-0ubuntu1
- Kernel: 4.8.0-30 (x86_64)
- Video driver: xorg-video-intel 2:2.99.917+git20160706-1ubuntu1

Doing the above results in Unity/compiz crashing with the following debug output:
Thread 1 "compiz" received signal SIGSEGV, Segmentation fault.
