Hi again,

I realized that I can back up to other versions of xorg-server by 
installing from the local directory that contains previous version 
downloads. I have discovered that ferret works fine with version 
1.12.0-1 of xorg-server (built 2012-03-12) and generates the 
segmentation violation with version 1.12.0-2 (built 2012-04-04).
