By backing up all the hidden files, then deleting all the hidden files 
and bringing them back in a few at a time and logging out and back into 
this account until the  crash occurred, I isolated the problem to a 
library path export in .bashrc.  See the inserted copy that follows.

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
     . /etc/bashrc
fi

# User specific aliases and functions
export FG_ROOT=/home/dad/FlightGear-git/fgdata
export 
FG_SCENERY=/home/dad/FlightGear-git/fgdata/Scenery:/home/dad/TerraSync
export HG2_DATA_PATH=/usr/local/games/hg2
#export 
LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/local/lib/osgPlugins:/usr/local/lib64:/usr/lib64
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/local/lib/osgPlugins
export 
PATH=$PATH:/sbin:/usr/sbin:/usr/local/sbin:/usr/local/bin:/usr/local/share/OpenSceneGraph/bin:$JAVA_HOME/bin:/usr/include

The commented out export LD_LIBRARY_PATH causes gnome3 to crash

The next line is a copy of that line w/o reference to the lib64 
libraries and this does not cause gnome3 to crash.  This is clearly a 
bug that was introduces a week or so ago by an update.

I should have mentioned this is FC16 x86_64 fresh install from the DVD 
iso that has been been kept up-to-date with yum.
