Danger with NVIDIA drivers 180.29

Note that this had nothing to do with the fact that the driver came in a RPM Fusion-provided package, it's just that the issue was first(?) reported on RPM Fusion's developers' list, because the reporter was using Fedora with RPM Fusion repos enabled for easy nVidia driver installation. See https://bugzilla.rpmfusion.org/show_bug.cgi?id=433 for more details.
