Bug#551647: It's libglib2.0-2.22.2-2

[Andrew Stone <stone@nyu.edu>]

From /var/log/messages:

kernel: [ 1848.349475] compiz.real[5158]: segfault at 7f15bf79fd68 ip 
00007f15bf9e1faa sp 00007fffd4dce240 error 4 in 
libglib-2.0.so.0.2200.2[7f15bf9a4000+c4000]

This problem is being reported everywhere, and all of them are dealing 
with the same glib version.  I downgraded to 2.16.6-2 (the only lower 
version I could still find in the repos), and despite almost nothing 
else working, I was able to get some compositing going, and compiz 
clearly loaded.

I'm not entirely sure where to go from here, so I'll leave it at that...
