F7 Screen saver resets X

[Paul Lemmons <paul.lemmons@xxxxxxxxx>]

I upgraded to F7 from FC6 and it appeared to run cleanly. I then updated 
the system (303 packages) and that went cleanly. Everything seems to be 
working, so far with one major exception. When my screen saver kicks in 
it resets X. Even in the kcontrol when I select the screen saver and it 
starts the preview it crashes X. I have looked in my Xorg.0.log, 
messages and dmesg with nothing jumping out at me as a probable cause.

Any clues from anyone?
