XScreensaver-demo not starting when normal user
 

Within the past several days to a week I have been unable to launch 'xscreensaver-demo' either via the GUI or at a shell prompt as myself. However, I am able to launch it as root. Thus the program itself is fine. My screen still locks etc. just fine, but I am just unable to change my screensaver. When I am in a terminal and try to run 'xscreensaver-demo' as myself I get a segmentation fault.
I am using GNOME.

Any thoughts?
