[CentOS] Using nVidia driver, screensaver issues

The nVidia driver is running right, but now when I try to select some screensavers, like Anemotaxis, X restarts.

/var/log/Xorg.0.log.old show it aborting on a signal 11...

These 3 (now wrapped) lines show up in the system log... Apr 12 15:45:51 hack-f dbus: Can't send to audit system: USER_AVC pid=10939 uid=500 loginuid=-1 message=avc: 1 AV entries and 1/512 buckets used, longest chain length 1 Apr 12 15:45:52 hack-f gdm[10665]: gdm_slave_xioerror_handler: Fatal X error - Restarting :0 Apr 12 15:45:52 hack-f gdm(pam_unix)[10665]: session closed for user dw49

Hmmm... time to dig further, and select a different screensaver. :)
